Declare compatibility with Drupal 9.
Signed-off-by: Chris Gilligan chris-gilligan@utc.edu
Added core_version_requirement key and ^8 || ^9 value to make Composer happy.
Use $relative_autoload_path parameter, available since Drupal 8.8 via function autoloadPath, instead of the deprecated methods:
- hardcoded relative path (which does not work with all projects), or
- commented out path, which presumes Composer Merge.
