Revert "[CVE Fixes] Update version of Nimbus.jose.jwt (#16320)" (#16986)

This reverts commit f1d24c8.

Updating nimbus to version 9+ is causing HTTP ERROR 500 java.lang.NoSuchMethodError: 'net.minidev.json.JSONObject com.nimbusds.jwt.JWTClaimsSet.toJSONObject()'
Refer to SAP/cloud-security-services-integration-library#429 (comment) for more details.

We would need to upgrade other libraries as well for updating nimbus.jose.jwt
