Bundled themes: block-patterns.php file should use `get_template_directory_uri` instead of `get_stylesheet_directory_uri`

In Bundled Themes, the block-patterns.php file should use get_template_directory_uri instead of get_stylesheet_directory_uri to avoid issues with child themes.

Good catch!

Twenty Ten, Twenty Eleven, and Twenty Twelve appear to be the only affected themes. The rest are already using get_template_directory_uri() for images in inc/block-patterns.php.

In 51483:

Bundled Themes: Use correct path for loading images in block patterns.

By using get_template_directory_uri() instead of get_stylesheet_directory_uri(), we make sure to include the images from the parent theme.

This avoids displaying missing images in block patterns when using a child theme of Twenty Ten, Twenty Eleven, or Twenty Twelve.

Follow-up to [51033], [51103], [51106].

Props audrasjb.
Fixes #53769.

Reopening for backporting to the 5.8 branch.

[51483] looks good to me for merging in to the 5.8 branch.

As fatal errors are quite bad, I think version bumps should be committed on this ticket and quick turnaround releases done with a single fix for the affected themes.

In 53769-version-bump.diff​:

• Twenty Ten becomes 3.5
• Twenty Eleven becomes 3.9
• Twenty Twelve becomes 3.5

Bumps in readme and style.css; change log added to readme (todo: codex update).
