[CI] Run make notice linting

[v1v]

What does this PR do?

@jsoriano pointed that the make check didn't run when go.mod changes:

Beats keep a NOTICE.txt file with references to the copyright statements of third party libraries.
This file should be up-to-date with the libraries used, for that, CI should be able to detect changes in dependencies so we don't forget to update this file, and it used to.
Recently a new dependency was added in #23484 (or #22541), without updating the NOTICE.txt file, and CI didn't detect it. We found the issue when it was detected in other PRs like #23536. This was fixed in #23549.
So it seems that this is being detected in some PRs and not in others, we should be able to prevent these issues in CI as they can be important for license compliance, and to prevent us including dependencies on software with forbidden licenses.

Why is it important?

Ensure there are no missing licenses in the NOTICE.txt file.
