Detect typos in Markdown documents (2nd attempt)

[electrocucaracha]

Problem

Typos and grammar errors are not easy to detect, specially when documentation is created with standard editors. This becomes harder for non-native English speakers.

Change overview

This change fixes some of the current existing typos in the markdown documents as well as provides a set of GitHub actions for reviewing new changes and/or additions in documents.

Testing

The GitHub actions will only be triggered when changes on markdown are detected.

@electrocucaracha This doesn't pass restyled, looks like it's struggling with the .github workflow, and the wordlist. How did we seed this wordlist with things like aabbccddeeff, also - can you check restyle here locally to see if this passes for you?
