HFJ_RES_VER_PROV might cause migration error on DB that automatically indexes the Primary Key

[TynerGjs]

Describe the bug
When updating from hapi-fhir version 6.6.0 to the newest version, data migration will throw error when trying to add index on column RES_PID of HFJ_RES_VER_PROV table since it is already indexed in previous version.

To Reproduce

1. Run hapi-fhir 6.6.0 with fresh OracleDB 12c. Notice data migration will happen automatically.
2. Stop hapi-fhir, and replace with newer version (e.g. version 6.7.14) on the same database.
3. Run hapi-fhir.

Observed behavior

ca.uhn.fhir.jpa.migrate.HapiMigrationException: 
   HAPI-0047: Failure executing task "Add IDX_RESVERPROV_RES_PID index to table HFJ_RES_VER_PROV", aborting! 
   Cause: ca.uhn.fhir.jpa.migrate.HapiMigrationException: HAPI-0061: Failed during task 6.8.0.20230510.2:

   SQL state [72000]; error code [1408]; ORA-01408: such column list already indexed; nested exception is java.sql.SQLException: ORA-01408: such column list already indexed

Expected behavior
