CI: Add gofmt check in lint

[singh1203]

Fixes: #58

What changes are included in this PR?

Added the gofmt check in the pre-commit-config.yml, which identifies files that need gofmt linting and make proper linting.

Are these changes tested?

Yes, I tested it on my forked repository example here

Would it make more sense to include this in the golangci configuration that we use with pre-commit instead? Particularly if we could have it so that pre-commit runs gofmt for the user too

Yes, you are correct. I raised the same question in yesterday's Arrow community meeting. I will incorporate the changes as per the review.

@zeroshade I made changes by adding a hook, which you can see here. This raises the question: do I need to commit the changed files after running pre-commit cmd locally?
