Added github actions for PRs (#3) 
* Added github actions for PRs

* Added some rustfmt::skip attributes

* Applied formatting

* Added rustfmt component in action

* Configured to use rustfmt version 2 which fixes some comment formatting

* Removed ready_for_review condition for github actions

Since it has the synchronize condition, it will update after each
commit, whether in draft or not, so I think this should be alright
