Subject: builder.yml: Reinstall vagrant(-libvirt) if needed
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=81e38dda545b34ac4c3872303cb706b6eacfdda3;p=ceph-build.git

builder.yml: Reinstall vagrant(-libvirt) if needed

Avoids:

```
Vagrant failed to properly resolve required dependencies. These
errors can commonly be caused by misconfigured plugin installations
or transient network issues. The reported error is:
nokogiri requires Ruby version >= 3.2, < 4.1.dev. The current ruby version is 2.7.4.191.
```

Which happens when an old vagrant version is installed on a builder then the version of vagrant provided in the chacra repo is newer.
