Revert "[CVE Fixes] Update version of Nimbus.jose.jwt"

[pagrawal10]

Reverts #16320

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

@pagrawal10 Whats other libraries need to get bumped up ?

[pagrawal10]

We need to bump up druid-pac4j as well. I have created a PR for the same: #16567
We would need to add it as a different extension as that would not be compatible with JDK8.
pac4j versions > 5 are compatible with only JDK 11 and above
import needed is also different for pac4j v4.5.7 and pac4j v5.7.3 :
import org.pac4j.jee.context.JEEContext;
vs
import org.pac4j.core.context.JEEContext;
