Is your feature request related to a problem? Please describe.
We don't check correct prettier formatting of code before commit, though we do have lint checks.

Describe the solution you'd like
Use the scripts defined in package.json and check for formatting before every commit.

Closing. This doesn't seem valid

1. Sorry about the hasty closing of the issue and PR
2. Your PR didn't address the formatting. Why?

[lakshz]

1. on the first commit in the PR, I added npm run format:fix in the husky file, which fixes formatting in all the code files.
2. but then I found that lint-staged is already configured to format the staged files. And, it works fine. So, I restored the husky file.
   

if we want to format all code before committing, issue remains open. Else, we can close this.

(In talawa-admin, pre-commit formats full code https://github.com/PalisadoesFoundation/talawa-admin/blob/main/.husky/pre-commit )

PS: The issue was raised because I'd to fix the formatting and re-push my changes in my other PR #1774, maybe I was not on the latest code, and that's why the GitHub PR workflow format check was failing.

OK, that makes sense.
Thanks for the clarification.
