We've been bitten by this issue many times in the past: if a dependency upgrades to a newer Jandex than what Quarkus contains, build fails with an `UnsupportedVersion` exception.

This commit is a proper solution: if the exception is thrown, we swallow it and reindex the archive with the Jandex version that Quarkus incorporates.

Further, this commit increments the minimum Jandex version we "trust" from Jandex 2.1 to Jandex 3.0. We rely on new features from Jandex 2.4 and 3.0 on many places, so it makes sense to make 3.0 the new minimum. The changes added in 3.2 and 3.3 are also important, but are not used heavily yet.
