code review: revert build-workflow addition from #551

[egpbos]

This is a belated review of #551.

I don't see what the addition of the build.yml workflow adds to CI. The useful part of the pre-existing workflow was to run the tests. Installing the template repo as a package is not a goal in itself, so we need not test it separately.

Related to #651. What I would suggest is that we just rename build.yml to lint.yml and remove the build workflow from the file, killing two birds with one stone.

Never mind, I see the other issue is actually about the generated package. So my suggestion here is to just remove build.yml in the template.
