FINERACT-2147: fix extra swagger UI endpoint paths

I noticed an extra `v1/` while visiting https://localhost:8443/fineract-provider/swagger-ui/index.html

All fineract-provider (unit) tests passed.

I also manually tested out hitting a few /api/v1/ endpoints via the Swagger UI web page at the URL above and those worked as well.
