Replace branches 3.7 - 4.0 update notices

[peterwilsoncc]

Follow up to #56532.

The WordPress Security Team will cease providing updates for WordPress versions 3.7 – 4.0 as of December 1, 2022.

The new strings were added for translation preparation in #56532 and need to be implemented for display in WordPress versions 3.7 through 4.0

In the ​linked pull requests:

• Notification changes from the original patches
• Version bumps
• About page updates

For the about page, I've labeled the fixes as security releases. There are not any existing strings for "this is the final release of WordPress x.x" so the existing string labeling them as security fixes was chosen as a best fit.

Thanks @audrasjb, I've addressed this in each of the pull requests relating to this ticket.

Note: based on a quick search this is a new string (it's not even in trunk). My understanding is that this shouldn't be too big of a problem, but it would be a good idea to get it in to core.

Thanks!
Yes, you're right, the string doesn't exist in core for now.
I see you opened ticket 57216 for this, I'll send a PR this morning :)

I've split the ​linked pull requests up in to two for each release: one to update the nag, the other for the version bump and about page update.

The new PRs contain code that @audrasjb approved earlier when they were bundled with the update nag notices.

wp-eol-scripts.zip​ contains the scripts I'll be running on the day.

Ok, it looks great to me, I approved the split PRs.
By the way, not sure the ticket milestone should be 6.2 🤔
Maybe rather WordPress.org? It doesn't make much more sense, but with this, it won't be attached to a 2023 release 🤷‍♂️
