Add details about rolling restart behavior

[jeanfabrice]

Make it clear that stepping over a version that triggers a restart still triggers a restart

@thbkrkr Thanks! I checkout from the wrong branch (2.7), not sure how I can fix this from a commit perspective. Trying to rebase on main raises tons of conflicts. Same merging main into this one...
Not a Git expert Should I create a new PR, closing this one?

You can open a PR or force push a new branch, as you want.

# if this repo is the remote 'upstream'
g fetch upstream  # optional to update your local main
g co main
g rebase upstream/main # optional to update your local main

g co -b jeanfabrice-docfix-rollingrestart-2 
g lg jeanfabrice-docfix-rollingrestart | head -2
g cherry-pick 6fa4461d3 && g cherry-pick bff575791

# if your fork is the remote 'origin'
g push -f origin jeanfabrice-docfix-rollingrestart-2:jeanfabrice-docfix-rollingrestart

Destination branch has been changed for main. Thank you @thbkrkr!
