This PR adds the link to the KB article about updating the mode after the upgrade to the 5.1 upgrade guide.
In addition, I have:
- updated the KB article to include the versions affected by that change.
- fixed the broken link to the page about metric updates (it is not related to the KB article, but I fixed it in the same PR to limit the number of PRs that need to be backported).

Fix https://github.com/scylladb/scylladb/issues/11373
- Updated the information on the "Counting all rows in a table is slow" page.
- Added COUNT to the list of selectors of the SELECT statement (somehow it was missing).
- Added the note to the description of the COUNT() function with a link to the KB page for troubleshooting if necessary. This will allow the users to easily find the KB page.
