Bump bundled theme versions for 6.0.0 release

[peterwilsoncc]

All bundled themes from 2010 to 2022 will need a version bump for the 6.0 release.

https://core.trac.wordpress.org/ticket/55754

[peterwilsoncc]

I've linked a pull request to this issue. I still have a couple of themes to test before it's ready.

[peterwilsoncc]

The ​linked pull request is ready for review.

I've bumped the theme number of all the bundled themes as they've all had some work over the last few months. All of them have had improvements made to the translator comments so it will be good to get those in to the project.

When reviewing the pull request please take a look at the ​themes directory and let me know if there are any asset version bumps that I have missed.

A few of them get the theme version from wp_get_theme() so not all themes that have had asset changes need a version bump.

If you're a committer and notice something needs work, feel free to push to my branch. Especially if I am asleep.

I checked all of them and look perfect to me

@desrosj @costdev I think I've caught all of the _tested up to_ bumps that are required now. Thanks for catching that.

It looks like several other styles and scripts did not have their versions bumped. I had always just assumed that the theme version was used, but seems that for older default themes, that's not the case.

@peterwilsoncc what do you think about changing all of these date versions to be accurate now? Or, we could just open a follow up ticket.

I reviewed ​the commits in the `wp-content/themes` directory and manually bumped the assets that had changed.

I think using the theme version is a good idea but let's use a follow up ticket. For themes with build tools it might we worth using wp-scripts to generate the version as it will be more performant. But let's discuss that there.

Themes: Accept valid block themes.

Updates theme validation to accept block themes. This replaces the requirement for an index.php with a requirement for either an index.php, /templates/index.html or the deprecated /block-templates/index.html.

Validation is updated for theme uploads, within WP_Theme::__construct and validate_current_theme().

A block theme using the deprecated file structure is now included in the unit tests.

[53418] looks good to backport.

For reference, just noting that #55682 was the correct ticket for [53416].

While preparing the theme updates for release, I noticed that Twenty Ten did not actually have any changes to the actual source code during the 6.0 cycle.

It looks like adding the Changelog link to the readme.txt file was missed last time around. This can be updated independent of an actual theme update that is deployed to potentially 1.2 million+ sites (total number of sites with Twenty Ten installed).

Post-release, let's un-bump the version for that theme and get the readme.txt updated on .org.

No functional changes were made to Twenty Ten during the WordPress 6.0 release cycle so the theme version bump is not needed. The "tested up to" header change is maintained.
