Comment (by Bernhard Reiter):

 I made a mistake when writing the commit message, so a number of changes
 that go beyond the npm packages version update aren't documented there.
 I'll cover those here instead:

 - Amend the `replace:source-maps` Grunt task to remove source map URLs
 (added by `react-spring`) from the block-editor build that would otherwise
 be flagged by the `verify:source-maps` task.
 - Modify the `copy:block-json` Grunt task to include line breaks (and
 indentation) in the `block-json.php` file it generates, as that file was
 rejected by a pre-commit SVN hook on the server due to all of its contents
 being on just one line.
 - Rewrite a number of calls to `str_contains` and `str_ends_with`, which
 are only available in PHP 8+ and are polyfilled by WordPress for earlier
 PHP versions, as some of them are called even before WordPress' compat
 layer is loaded, thus leading to fatals on earlier PHP versions.
