Still has dependency on linkchecker ^1.0@beta which is not compatible with Drupal 10

Linkchecker Summary Email still has a dependency on linkchecker ^1.0@beta which is not compatible with Drupal 10. When I run:

composer require 'drupal/linkchecker:^2.0@alpha'

This is the output I get:

Problem 1
- Root composer.json requires drupal/linkchecker ^2.0@alpha, found drupal/linkchecker[2.0.0-alpha1] but these were not loaded, likely because it conflicts with another require.
Problem 2
- drupal/linkchecker_summary_mail dev-2.0.x requires drupal/linkchecker ^1.0@beta -> found drupal/linkchecker[1.0.0-alpha1, ..., 1.1.0] but it conflicts with your root composer.json require (^2.0@alpha).
- drupal/linkchecker_summary_mail 2.0.x-dev is an alias of drupal/linkchecker_summary_mail dev-2.0.x and thus requires it to be installed too.
- Root composer.json requires drupal/linkchecker_summary_mail 2.0.x-dev@dev -> satisfiable by drupal/linkchecker_summary_mail[2.0.x-dev (alias of dev-2.0.x)].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

I believe linkchecker_summary_email should now require 'drupal/linkchecker:^2.0@alpha'
