[8.13] Update link in 8.8 release notes (backport #5463) (#5465)

* Update link in 8.8 release notes (#5463)

This link points to a setting that's in the wrong area of the Fleet & Agent docs, so before I can fix that I'd like to update this link, in order not to bust the docs build.

This link originates in version 8.8 so I hope it's okay to backport to there.

(cherry picked from commit 32e56e2)
