Add inline block support for Github / NPM badge, tweak labels

[arcataroger]

Small improvements to the new badge functionality:

1. Tweaked Github labels to better support some of our monorepos with very long paths
2. Added inline block support so it can be used as a span too

Hey @arcataroger, the label tweaks for long monorepo paths (point 1) are a nice improvement 👍

However I'm not a fan of the inline block support (point 2). These GitHub/NPM badges are not meant to be used inline within running text — it looks odd and breaks the reading flow. In the wild, badges like these are always used as a standalone "header" block at the top of READMEs or doc pages, never sprinkled inside paragraphs or list items as spans.
