Normalization of package names according to PEP503

[kse3hi]

          I go a little bit deeper, and figure out that PEP503 is obligate to normalize names of packages and replace all `-`,`.` and `_` with `-`.

LInk: https://peps.python.org/pep-0503/#normalized-names

As far as it is required renaming and releasing new package, and can lead for inconsistency, I've decided to separate this activity with the new task.

@kse3hi: What actually needs to be done here? All our repos already follow that pattern (just lowercase letters + '-') ...

It is not about repository names, it is about python package, that wir are releasing. E.g. "velocitas_sdk" vs. "velocitas-sdk"
