Remove stack-yaml-generated-is-valid pre-commit hook

What do these changes do?

Remove stack-yaml-generated-is-valid pre-commit hook

Rationale
This hook relies on .config.location and on manually generated repo.config in osparc-config repository. This pre-commit hook will fail for any new user trying to commit to the osparc-ops-environments since these users are unaware of the dependency on repo.config from osparc-config repository. Moreover, any non-ITIS user cannot even get this repository (hence commit at all) since it is not publicly available.

UPD:
The idea of pre-commit hook relying on physical generated files from other repositories seems to be wrong. This is why in our GitHub CI we cannot run pre-commit as is (we have to skip stack-yaml-generated-is-valid hook)

I can agree with what you wrote, this test was useful some years ago when it still worked properly, but not anymore. Thanks!
