Get rid of the dependency check

[ndr-brt]

WHAT

...and provide it before the release

WHY

In TRG 7-04 is stated that it's not necessary to keep the DEPENDENCIES in the repository and have it checked on every commit.
The check can happen once right before the release, and the file can be published on github pages for reference.

This needs to be done also on other repos under the edc subdomain: bdrs, compatibility tests and so on...

HOW

• add dependencies check right before the release
• commit the DEPENDENCIES file during the release
• generate and publish the DEPENDENCIES file to github pages on every commit on main branch
• change NOTICE file to point to the github pages published DEPENDENCIES file
  Bonus:
• add automatic job that nightly (but also on every commit!) request IPlab review for restricted/rejected dependencies (so the check before release will likely pass all the time)

FURTHER NOTES

inspiration can be taken from the upstream EDC process:

• dependencies check during release preparation (notice the "strict" flag)
• generate dependencies file action
• publish dependencies file to github pages on every push to main
