Bundled themes: Update schema version in style variation files

[poena]

In #61342 the schema version in theme.json was updated in Twenty Twenty-Two, Twenty Twenty-Three and Twenty Twenty-Four.

The style variation files in the styles folder must also be updated.
If the style variation has the wrong schema, code editors that support schema may show that settings or styles are invalid.

In case the style variation does not have a schema, it should be added.

The version that should be added is 6.5. Example:

"$schema": "https://schemas.wp.org/wp/6.5/theme.json",

Documentation:

Hi @umeshsinghin thank you for the pull request.

The schema needs to be

"$schema": "https://schemas.wp.org/wp/6.5/theme.json",

not

"$schema": "https://schemas.wp.org/wp/6.6/theme.json",

This is because the themes are using Theme.json version 2.
6.5 is that latest schema for version 2.

It also needs to be added to Twenty Twenty-Two.
