Document Jwt Client Authentication support in the reference.

Issue gh-9520

Thank you @jgrandja for your efforts in adding jwt client authentication support to spring security! I am currently trying to test the private_key_jwt method with 3rd party provider within a spring boot app but I am failing to see how would I set it up properly. I already looked at the test cases you mentioned in gh-9520 but since this is new stuff for me I am still puzzled.

Can you share a working example code/configuration that I could mimic?

@siren I'm planning on putting together a sample along with the documentation. I'll get to this later next week.

Hi,
I'm looking for a working example of private_key_jwt with client_crendentials, but I can't find the version with ServerOAuth2AuthorizedClientExchangeFilterFunction (no ServletContext), but only with OAuth2ClientCredentialsGrantRequestEntityConverter in a ServletContext.
Can you add a working example please?
thanks
