merge package.json and GitHub topics, update and cleanup libraries

[Simek]

Why

Refs #484

This PR improves the topics gathered for library and search string generation. The current flow has been simplified and package.json keywords will be always extracted. For non-monorepo packages also the GitHub topic will be added (and the merge list will be deduplicated).

This is not the full fix for the reference issues, but it should improve the search UX a bit.

Example of updated tags for audio-toolkit

In addition the topics are being processed to address the whitespace character allowed in package.json keywords.

During work on the changes I have noticed one deleted library and few small warnings about moved packages - those problems have been also addressed.

The last thing included in this PR is updated libraries:cleanup script which includes now prettier step like the pre-commit hook, so the cleanup results are consistent with final reformat.
