I'd like to be notified about weird vulnerabilities in JavaScript
libraries for the release branch as well. It's double important
since the release branch ships particular pinned version of *all*
dependencies.
It's not like we need any new features, but let's bump the versions
because we are in JavaScript land.
Also, run "npm audit" regularly, just in case a serious vulnerability
is discovered.
Well, it seems the environment is changing so we'd better run the tests
reguarly to see whether something breaks in a timely manner.
GitHub Actions also don't offer other Windows environments now, only
windows-latest is available. Reduce test matrix to only that.
Try compiling some C code, If it works then we're probably fine.
I don't even try to verify cross-compilation because I don't need it.
It should work, but that's not my problem right now.
Now that I know how to write some simple action, let's make a stub
more complete. For example, I already know what inputs I would like
to handle for this action.
