packit uses wrong version in fix-spec-file step if PR bumps version
Example PRs:
- https://github.com/theforeman/foreman_maintain/pull/688
- https://github.com/theforeman/foreman_maintain/pull/686

Our `.packit.yml` contains the following `get-current-version` action:
```yaml
  actions:
    get-current-version:
      - ruby -rrubygems -e 'puts Gem::Specification::load(Dir.glob("*.gemspec").first).version'
```
This reads the actual version of the software from the gemspec and works just fine usually.

However, when we bump the version (as in the PRs linked above), the version is correctly detected by the action but seems not to be used *everywhere* in the code.

Looking at the SRPM [buildlog](https://download.copr.fedorainfracloud.org/results/packit/theforeman-foreman_maintain-686/srpm-builds/05557745/builder-live.log.gz) I see:

```

Given `Source0` is gem, not a "real" tarball with folders, `get_archive_root_dir_from_tar` returns `None` and so `get_archive_root_dir` continues to use `get_archive_root_dir_from_template` which then uses the version from the spec file (`1.2.4`) and not the one we just generated (`1.2.5`).

This results in a RPM spec having `Version: 1.2.5` (which is correct), but then later using `%setup -q -n  foreman_maintain-1.2.4` and that obviously fails :)

Our spec file (before fix-spec-file) uses `%{version}`, so having #1736 would avoid the issue (and so would using a custom `archive_root_dir_template`, maybe something like `%{gem_name}-%{?version}` so that the `{version}` part is not replaced), but that seems like a bandaid.
