# Pull Request

## Description
This PR addresses an issue where `commit-lint` job crashes when
validating pull requests.

## Changes Made
Currently, the commitlint config file is getting loaded as an ES module
whilst it contains vanilla javascript configurations. This causes the
job to crash because it expects a common javascript config but finds an
ES module config. To address this issue The commit-lint config file has
been changed to a `common-js` file instead of a `js` file and the
conventional commit dependancy will now be installed during the job via
npm.

## Screenshots (if applicable)
After making the changes, I tested the commit-lint job locally and here
is an excerpt of the execution:
