@sberyozkin This is a quality update for `main`.
Do you approve backporting it to `3.2` as well?

Note: Here, I've made minimal changes to fix Vale errors and some warnings for content in the `*.java` source files that go into the `_generated/config/quarkus-oidc.adoc` file.
This generated content makes up the bulk of the [OpenID Connect (OIDC) Configuration Properties](https://quarkus.io/guides/security-oidc-configuration-properties-reference) reference guide, which we are making available for RHBQ.
