[tejasdrolia]

This PR is to fix non FIPS compliant TLS usage in artifact-manager-s3 , this is done by ensuring that useHttp flag is not allowed to be true while operating in FIPS mode.

Testing done

• Automated Unit Testing:

Added a dedicated unit test S3BlobStoreConfigTestFipsEnabled to validate that setting the useHttp flag to true while in FIPS mode results in an Error , ensuring compliance.

• Manual Testing:

Did Manual testing to verify my changes to ensure that everything is working properly.
