FINERACT-2336: improve asciidoc post-1.12.1 release

* update release notice years in NOTICE_RELEASE and NOTICE_SOURCE
* step 5
  * simplify mention of tests: "Ensure all tests pass for this commit both in CI and locally"
  * recommend GPG signing annotated release tag
* step 8: improve svn commands
  * This way is simpler and more efficient, especially with a bunch of release candidate dirs in the staging area.
* step 10: mention need to test rc before +1 vote -- See:
  * https://www.apache.org/legal/release-policy.html#release-approval
  * https://www.apache.org/legal/release-policy.html#approving-a-release
* step 12: only PMC members can upload releases
* step 13: simplify & explain "finalize branch" instructions
  * Document what worked for me for 1.12.1.
  * I didn't need to create the extra `merge-$VERSION` branch and do the recursive merge.
* document how asciidoctor upgrade is blocked
  * see "official docs - deps stuck" thread on fineract dev mailing list
  * https://lists.apache.org/thread/7mmsj13spb11vgz0z38fhwgzwtq03brr
  * can't upgrade to 4.x because of one of these:
    * https://github.com/asciidoctor/asciidoctorj-pdf/issues/25
    * https://github.com/jruby/jruby/issues/5573
    * https://github.com/asciidoctor/asciidoctorj-pdf/issues/16
* improve asciidoc config - opt for simplicity where the complexity adds nothing
  * compat-mode is off by default, no need for it here
  * default optimization should be fine
  * media should have been screen | print | prepress, just leave it as default instead
  * page size? I really don't think this is going to be printed much, just go with default
  * PDF version 1.8 is invalid, just use the default unless we someday have a good reason to pin this
  * reduce copyright years sources of truth
  * see also: https://docs.asciidoctor.org/pdf-converter/latest/asciidoc-attributes/
* remove unnecessary asciidoctorj 3.0.0 version string -- no need to pin this
* remove prompt character from Bash shell examples
  * it isn't properly syntax-highlighted and it looks confusing with line numbers (which we might want to add)
  * it isn't necessary
  * the prompt character ("%" in this case) is not typically included in shell code examples because it makes it harder to copy and paste shell code examples
  * $ is likely more common than % (at least on Debian/Ubuntu), but either way I'd say exclude it
* fix source code syntax labels - use "bash" only when it is actually Bash shell code
* persistence.adoc
  * fix broken enumerated list
    * resolves these warnings seen with, e.g.: `gradle --info doc`
    * `Jul 27, 2025 8:26:48 PM uri:classloader:/gems/asciidoctor-2.0.10/lib/asciidoctor/parser.rb parse_list_item`
    * `WARNING: chapters/architecture/persistence.adoc: line 104: list item index: expected 1, got 2`
    * `Jul 27, 2025 8:26:48 PM uri:classloader:/gems/asciidoctor-2.0.10/lib/asciidoctor/parser.rb parse_list`
    * `WARNING: chapters/architecture/persistence.adoc: line 110: list item index: expected 1, got 3`
  * fix wrapping (we use hardbreaks)
  * fix typo: `s/plane text/plain text/`
* switch to rouge syntax highlighter - it handles more source languages
* fix broken long shell code lines
* fix .avro file syntax highlighting (it's JSON)
* configuration-gpg.adoc
  * fix accidental block continuation
    * One little plus sign was making `= Email` appear verbatim in rendered output because it was interpreted as a list continuation.
    * See https://docs.asciidoctor.org/asciidoc/latest/lists/continuation/#list-continuation
  * recommend more secure keys
  * add a line continuation for an enumerated list
* architecture-overview.puml: remove this unused (likely a "Hello World") diagram
* release-schedule.puml: fix pluralization of days
  * purely aesthetic: doesn't affect chart rendering
* fix src/bin/binary tarball name typos
  * missed a few in e090da2a01
* fix release branch name
  * must match `release/{revnumber}`, per gitVersioning stanza in top level build.gradle
* harden.adoc: fix broken link to CISA
* fineract-doc/build.gradle
  * ensure HTML task has diagrams and images availble
