Bump default theme versions for WordPress 5.7

[desrosj]

The release of 5.7 will be accompanied by a release for each maintained default theme:

Twenty Twenty-One: 1.2
Twenty Twenty: 1.7
Twenty Nineteen: 2.0
Twenty Seventeen: 2.6
Twenty Sixteen: 2.4
Twenty Fifteen: 2.9
Twenty Fourteen: 3.1
Twenty Thirteen: 3.3
Twenty Twelve: 3.4
Twenty Eleven: 3.7
Twenty Ten: 3.3

The versions need to be bumped appropriately.

Reopening to backport to the 5.7 branch.

The diff looks good to me, it just bumps version numbers.

Seems fine for backport.

I forgot to follow up on this after 5.7 was released, but because there were only minor inline documentation and a date change to the license file, version 3.4 of Twenty Twelve was not released.

I'll bump the version back to 3.3 so that 3.4 is not accidentally skipped.

In 50596:

Twenty Twelve: Change theme version back to 3.3.

Because the changes in Twenty Twelve did not impact site look or functionality, version 3.4 of Twenty Twelve was not released in coordination with WordPress 5.7.

This reverts the portion of [50508] relevant to Twenty Twelve, changing the version back to 3.3 so that version 3.4 is not skipped accidentally when there are changes that should be released.

See #52704.
