Revert "matomo: fix quoting in cleanup shell script"

[osnyx]

This reverts commit 861912f from #1279. The commit was intended for the fc-24.11-dev branch, as matomo4 might still play a role here in 24.05.

The list of files to be removed is the list for matomo5 after an upgrade.

Design notes

• Provide a feature toggle if the change might need to be adjusted/reverted quickly depending on context. Consider whether the default should be on or off. Example: rate limiting.
• All customer-facing features and (NixOS) options need to be discoverable from documentation. Add or update relevant documentation such that hosted and guided customers can understand it as well.

Security implications

• Security requirements defined? (WHERE)
  • undoes a change that went to the incorrect branch
  • change was never released so far, no customer impact of the revert.
• Security requirements tested? (EVIDENCE)
  • automated tests still pass
