Updated the user guide with new article + updated old content (#16955)

- more details on rate at which messages are imported from Gmail
- Settings -> Release deprecated to Settings -> Updates => this leads to
updating the file title, file name and the navigation files
- Support & Documentation accessible via Settings and no longer the nav
bar
- updated features out of the lab
- no more integration page
- added a new article with step by step on how to notify a teammate of a
note to review

docs.json is updated only for the English part
