Bug fixes

Bug fixes release following the new 3.6.0 minor:

• Fixed PHP warning 'Trying to access array offset on value of type null' when configuration is not updated correctly.
• Fixed upgrade path for Drupal 9 and versions below 10.2 (regression).
• Fixed malformed HTML tags in module's string translations.

This release drops compatibility with all versions of core older than 11.2, due to a backwards compatibility breaking change in core's Package Manager module.

A very minor update to the path of view.

• Fixed an issue with apostrophes in customer names not being handled well in the room reservation edit form
• Fixed an error when viewing list of event registrations
