[FEATURE] Add search for alias as option to the pagetree filter

When searching/filtering in the page tree for an alias,
you don't get any results. Search only works with id and page title.

Extend the query to search for the alias, if it is configured in the
user ts config (options.pageTree.searchInAlias)
