Bundled Themes: Add "Tested up to" in style.css

[kafleg]

Twenty Twenty theme is missing Tested up to in style.css and this is the required thing. I have added Tested up to: 5.8 in Github.

Tested up to is required and it needs to be mentioned in style.css

Thanks for this, @kafleg!

I've taken a closer look, and it appears that Twenty Twenty-One is the only bundled theme that currently has Tested up to in style.css headers. This was an intentional decision at the time because WordPress Core did not yet utilize this header (see comment:5:ticket:48517).

Since then, [47145] added support for required WordPress versions in Core, but Tested up to is still not supported by Core within style.css headers.

I was not able to locate a ticket in Trac to consider adding this support to style.css files, so this could serve as that. But more work would be required, as Core itself must have a reason to add support for this header.

An example of this could be adding "This theme has not been marked as compatible with your version of WordPress." messages to match those shown when working with plugins.

Twenty Twenty theme is missing Tested up to in style.css and this is the required thing.

Can you expand on the "required thing"? Is this now enforced for themes residing on WordPress.org? If I recall correctly, that was not the case previously (it was a soft requirement/suggestion).

@desrosj Yes, it was recommended before. But, while reviewing themes we used to ask theme authors to add them. But when the ​Theme Check plugin is updated to the newer version, Tested up to is now REQUIRED. You can also see the ​Requirements handbook about this.

@ravipatel Thanks for the patch.

In 52221:

Bundled Themes: Update the “Tested up to” header to 5.9.

This updates the “Tested up to” header in the readme.txt file for all bundled theme.

This also adds the “Tested up to” header to the style.css file for older default themes (Twenty Twenty and earlier). Previously, this header was only recommended, so it was not included. It is now required, per the theme handbook: ​https://make.wordpress.org/themes/handbook/review/required/#9-files.

Props kafleg, mukesh27, ravipatel.
Fixes #53797.
