Closes #933

In this PR, we added a new custom Qute template function to filter OAuth methods by name since only one CompositeAuthenticationProvider class is required to process OIDC authentication per OAuth instance.

How to backport a pull request to a different branch?

In order to automatically create a backporting pull request please add one or more labels having the following format backport-<branch-name>, where <branch-name> is the name of the branch where the pull request must be backported to (e.g., backport-quarkus2 to backport the original PR to the quarkus2 branch).

NOTE: backporting is an action aiming to move a change (usually a commit) from a branch (usually the main one) to another one, which is generally referring to a still maintained release branch. Keeping it simple: it is about to move a specific change or a set of them from one branch to another.

Once the original pull request is successfully merged, the automated action will create one backporting pull request per each label (with the previous format) that has been added.

If something goes wrong, the author will be notified and at this point a manual backporting is needed.

NOTE: this automated backporting is triggered whenever a pull request on main branch is labeled or closed, but both conditions must be satisfied to get the new PR created.

Just a few nitpicks

[ricardozanini]

@fjtirado I made the resolve method a bit more complex so we can use isAssignable and avoid using ArrayList. But the real benefit is to remove the additional condition check in the template.
