Chore: Create pre-commit-hook

[Shivani-chourasiya]

Fixed #28

Changes proposed

Added .pre-commit-hooks.yaml file with the required keys to configure pre-commit-hook.

How to test?

Add the j2lint pre-commit hook inside your repository in .pre-commit-config.yaml.
Example-

 - repo: https://github.com/aristanetworks/j2lint.git
   rev: <tag/branch/sha>
   hooks:
   - id: j2lint

Run command: pre-commit run --all-files

Tested it on my local AVD repo by adding

  - repo: https://github.com/aristanetworks/j2lint.git
    rev: pull/35/head
    hooks:
      - id: j2lint

in my .pre-commit-config.yaml and it worked like a charm!

Thanks
