Fixup eachdist.py handling of package names (#5417)

* scripts/eachdist.py: tighter regexp for packages

While at it also introduce tests

* scripts: proper check of package name where to bupm version

Checking for substrings is not precise enough, let's check for the
metadata we have in pyproject.toml.

* update workflows

* Add missing opentelemetry-exporter-otlp-proto-common

* Remove non existant packages

* Add test to double check that all packages are accounted for
