No pre-checks on compatible releases which results on Notice: Undefined index: date in DrupalOrgClient

Problem/Motivation

Some values are getting empty data in the Drupal.org Client class

Steps to reproduce

Given that the "Project Browser" module was installed under Drupal 9.2.x
And logged in as the "webmaster" user no. 1
And cleared the cache
When navigating to "/admin/modules/browse"
Then the following notice will show up

Error message
Notice: Undefined index: date in Drupal\project_browser\DrupalOrg\DrupalOrgClient->Drupal\project_browser\DrupalOrg\{closure}() (line 216 of modules/contrib/project_browser/src/DrupalOrg/DrupalOrgClient.php).
Notice: Undefined index: date in Drupal\project_browser\DrupalOrg\DrupalOrgClient->Drupal\project_browser\DrupalOrg\{closure}() (line 216 of modules/contrib/project_browser/src/DrupalOrg/DrupalOrgClient.php).

Proposed resolution

Have pre-checks on compatible releases.

          if (!empty($compatible_releases)) {
            $project['releases'] = array_map(function($release) {
              return [
                'version' => $release['version'],
                'status' => $release['status'],
                'date' => $release['date'],
                'core_compatibility' => $release['core_compatibility'],
              ];
            }, $compatible_releases);
            $add_to_db[] = $project;
          }
