`set-output` command in GitHub linting action dependency is being deprecated

[Isgotkowitz]

GitHub Actions is deprecating the set-output command (read this), which is used in the linting action workflow. The dependency is get-changed-files by jitterbit.

Expected Behavior

The GitHub linting action should run without error.

Current Behavior

The GitHub linting action runs fine, but produces errors.

Possible Solution

For jitterbit's implementation, then make the changes and maintain it internally. This may be extremely easy, because someone has already done this in a PR.

Steps to Reproduce

1. Click on the linting "Details" button from any linting run, and expand the "Setting up dependency for getting changed files".
2. Scroll down and you will see the warnings.
