[BUG] Updating does not update default plugins when config is mounted

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

When updating Dokuwiki using the normal docker way, plugins are not updated if they are mounted. This is fine for regular plugins, since they update independently, but the built-in plugins cannot be updated manually and are stuck at whatever version you originally installed. Among other things, this leads to some settings not being available.

The problem was mentioned for instance here: https://github.com/dokuwiki/dokuwiki/issues/2372 .

It can be solved manually by copying in the plugins folders from a fresh install,

Expected Behavior

During an update, the built-in plugins are also updated.

Steps To Reproduce

1. Set-up dokuwiki.
2. Wait until Dokuwiki is updated, and update the container.
3. See that the built-in plugins are not updated.
