OpenIdAuthenticationMechanism ClassCastException when used with Microsoft Entra, expires_in as string

[Anodarai]

Microsoft Entra returns the expires_in field as a string, not a number eg.:
{"token_type":"Bearer","expires_in":"3599", (...)}
That causes a ClassCastException (class org.eclipse.parsson.JsonStringImpl cannot be cast to class jakarta.json.JsonNumber) in https://github.com/eclipse-ee4j/soteria/blame/e5f82534696f4b108f512701092b316cbb86584d/impl/src/main/java/org/glassfish/soteria/mechanisms/OpenIdAuthenticationMechanism.java#L498

While what Microsoft does here seems to be not to spec, I don't think it should cause the whole application to error out, instead it should log an error and continue, ignoring the value; or parse the string,

Thanks for the report. I'll look into it. The fix can be done without needing a reproducer, but to be 100% safe if you do have a reproducible setup to share, that would be awesome.
