What kind of change does this PR introduce?
feature (new workflow)

The workflow runs some checks on the plugin archive to make sure that everything is ok (especially important if processing the source code via php-scoper or Rector).

It executes Parallel Lint to check the PHP syntax, and Plugin Check phpcs ruleset, as well as other specified WP sniffs (by default I18n, because in some cases the translators: comments can be deleted by php-scoper).

It clones the Plugin Check repo and installs its composer deps, this seems to be the only quick way to use Plugin Check without WP and Docker, and it's a simple way to get phpcs and WP sniffs, since the plugin archive does not include the dev deps.

One issue here is that phpcs CLI is more limited than the config file. For example it’s not possible to ignore only the exception escaping errors when running the escaping sniff. But copying and maintaining the config for archive checking in each plugin seems like too much work, so for now trying like this.

Don't know if it is your use case, or if you really need it, but, see how we added a default config file here,
