Cannot create link to a collectives page from within a page template

Describe the bug
When editing a page template, it is not possible to create a normal inline text link to an already existing page within the same collective.

Selecting text and opening the link menu only offers:

• "Link to file or folder" (opens the generic Nextcloud Files picker)
• "Link to website"
• "Open Smart Picker"

None of these provide a way to search for and link to a page within the current collective the way "Link to page" does when editing a regular (non-template) page.

To Reproduce

1. Open a collective that has at least one page.
2. Go to "Manage templates" and create/open a template.
3. In the template, select a word.
4. Click the link icon in the toolbar.
5. Try to find an option to link to a page within the collective — no such option is available.

Expected behavior
It should be possible to select text in a template and create a plain inline link ([word](url)) pointing to an existing page in the same collective.

Start in the template editor's link toolbar and compare its available actions with the regular page editor's "Link to page" flow. Reproduce the issue using a collective with an existing page; done means selecting text in a template exposes a way to choose that page and creates a plain inline link to it.
