Extract the folder to extensions/TemplateStylesExtender.
Add the following to LocalSettings.php:

wfLoadExtension( 'TemplateStyles' );
wfLoadExtension( 'TemplateStylesExtender' );

Configuration

$wgTemplateStylesExtenderEnablePrefersColorScheme
Default: true
Enables or disables @media (prefers-color-scheme) queries.

$wgTemplateStylesExtenderEnableCssVars
Default: true
Enables or disables css variable support.

$wgTemplateStylesExtenderEnableUnscopingSupport
Default: false
Allows users with editinterface permissions to unscope css by setting a wrapclass attribute.

Note: This is potentially expensive, as each templatestyles tag with wrapclass set, will attempt to look up the user of the current page revision, and check if this user has the permission to activate css un-scoping.

Example: <templatestyles src="Foo/style.css" wrapclass="mediawiki" /> results in the css being scoped to .mediawiki instead of .mw-parser-output.

Note: Including such a call in a page essentially limits editing to users with the editinterface right. You can alternatively include a call to a template that includes the styles.

$wgTemplateStylesExtenderUnscopingPermission
Default: editinterface
Specify a permission group that is allowed to unscope css.

Notes on CSS vars

Currently using :root selectors won't work due to template styles prepending .mw-parser-output.

One possible fix is to wrap the entire content into a div element and adding the declarations to this, e.g.

div#content-wrap {
	--padding: 10px
}

.content {
	padding: var( --padding )
}

<div id="content-wrap">
	<div class=".content">

	</div>
</div>
