release: continue pestering until user upgrades

In 'git-update-git-for-windows', there is a recently_seen variable that
is loaded from Git config. This is intended to allow users to say "No, I
don't want that version of Git for Windows." If users say no, then they
are not reminded. Ever.

We want users of microsoft/git to be notified repeately until they
upgrade. The first notification might be dismissed because they don't
want to interrupt their work. They should get the picture within a few
reminders and upgrade in a timely fashion.
