Add Github actions to run wazuh check updates plugin tests on PRs

Description

When we upload changes to a PR, in addition to running the tests of the main plugin, the tests of the Check Updates Plugin should also be executed.

To automatically add a comment with the code coverage of the test for each plugin, it was necessary to fork the GitHub Action repository: https://github.com/marketplace/actions/comment-test-coverage. When adding a new plugin and generating multiple comments, this GitHub Action would remove all previous comments and only the last one would remain.

The new Github Action (https://github.com/marketplace/actions/comment-test-coverage-with-delete-filter-by-title) solves that issue and ensures that the last comment for each plugin remains.
