@var tag must not end with a full stop

Tested this with ag

ag "@var (.*)\."

core/tests/Drupal/Tests/Core/Asset/CssOptimizerUnitTest.php
23:   * @var \Drupal\Core\Asset\CssOptimizer object.

core/tests/Drupal/Tests/Core/Asset/CssCollectionGrouperUnitTest.php
18:   * @var \Drupal\Core\Asset\CssCollectionGrouper object.

core/tests/Drupal/Tests/Core/Asset/JsOptimizerUnitTest.php
18:   * @var \Drupal\Core\Asset\JsOptimizer object.

core/tests/Drupal/Tests/Core/Asset/CssCollectionRendererUnitTest.php
18:   * @var \Drupal\Core\Asset\CssRenderer object.

core/tests/Drupal/Tests/BrowserTestBase.php
142:   * @var string.

core/modules/quickedit/tests/src/Kernel/MetadataGeneratorTest.php
33:   * @var \Drupal\quickedit\MetadataGeneratorInterface.php

core/modules/views/src/Plugin/views/field/MachineName.php
21:   * @var array Stores the available options.

core/modules/editor/tests/src/Kernel/QuickEditIntegrationTest.php
41:   * @var \Drupal\quickedit\MetadataGeneratorInterface.php

Not sure if we should fix those @var declarations that have a php file as well in this issue, but the other ones should still be fixed.

This patch is also fixing semicolons, those are all ok.

#3 Fixed the occurrences mentioned in the comment, but I was unable to install ag on my Windows machine to check for new violations. Can you take a look?

Found a few more:

Fixed the violations mentioned in #6

I tried to run composer phpcs after applying this patch and couldn't find any remaining issues.

The patch looks fine except shouldn't it also enable the rule?

Shouldn't this just be 'int'?
