Restore dependency convergence of nimbus-jose-jwt

This commit reverts the change in 2801cdd which caused the
oauth2-oidc-sdk transitive dependency version of nimbus-jose-jwt to
diverge with the version depended on in spring-security-oauth2-jose.

The downgrade to 9.24.4 is intentional but the upgrade to 9.31 was not.

Issue gh-13333

Closes gh-13843
