Fixing the tenant annotation check order in the OIDC renant resolver

[sberyozkin]

This PR does a minor OIDC tenancy doc update, as the Table of content is misaligned right now starting from https://quarkus.io/version/main/guides/security-openid-connect-multitenancy#tenant-resolution-order, so hopefully, after this PR, it will be much clearer from TOC alone what the order is.
And it does a minor optimization/fix to the OIDC DefaultTenantConfigResolver to align it with the docs: if the @Tenant annotation was used to resolve the tenant id, calling the dynamic custom TenantConfigResolver is wrong, I missed it during the recent refactoring which is all still on main only
