fix: restore meeting notes links

[Codewithpabitra]

Fixes: #315
Fixes: #681

Description

Meeting minutes on the Community page were previously displayed only in a modal, while older direct links such as
/community/meeting/notes/2021-04-06/ returned 404.

This PR gives meeting minutes their own directly accessible pages and updates the Meeting Minutes links on the
Community page to point to those pages.

This restores access to existing meeting-note URLs and makes the notes bookmarkable and shareable.
