add review dog with shell check

[ishanrai05]

Status

Ready. Tested on my branch here

Description

I added a review bot that will comment on the line with the lint error and link to how to solve it. It only works on changed lines.

Is it backward compatible (if not, which system it affects?)

Yes

Mention people to look at PRs

@ishanrai05 why did you remove the action to work on push?

[ishanrai05]

pull request action will work even if we add a commit to our existing PR. I tested this on my branch on the link provided above. The push and pull request action are causing a double build.

@ishanrai05 yes but it won't work in case some one by mistake pushes directly to GH without a PR. so please change it to push and PR both. thanks.

reviewdog does not work on push event because it needs a pull request to leave comments on. So I created another yaml file which will run on push event.
