Install script is hard coded to watch theme ‘seven’

Problem/Motivation

The module has a hard coded installation configuration to watch theme ‘seven’ but does not/cannot declare it as a dependency. This results in a PHP error:

Drupal\Core\Extension\Exception\UnknownExtensionException: The theme seven does not exist. in Drupal\Core\Extension\ExtensionList->getPathname() (line 524 of /web/core/lib/Drupal/Core/Extension/ExtensionList.php).

Steps to reproduce

1. Create Drupal 10 site without the theme seven.
2. Install module scss.
3. Enable module scss.
4. Access SCSS Compiler form at Configuration -> Development.

Proposed resolution

Remove ‘seven’ as the default theme to watch.
