set-output command will be deprecated soon and upgrade to Node16.

Describe the bug
Recently we started seeing these warnings on github actions -

Warning: The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

Warning: Node.js 12 actions are deprecated. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/. Please update the following actions to use Node.js 16: jitterbit/get-changed-files

Looks like the action is internally using set-output command which will be disabled soon by github.

To Reproduce
Steps to reproduce the behavior:

1. Run a workflow using jitterbit/get-changed-files.

Expected behavior
Warning should not be seen.

Additional context
This action is really important for us and it is being used in an important workflow.

Following the blog post (one linked in the warning), it seems that the core.setOutput usage from '@actions/core' should be replaced with core.exportVariable. 🤔 I am not fully sure how to make this work without breaking changes though.

There is a related discussion in the actions/core here: actions/toolkit#1218

For anyone interested in this issue we forked this repo into https://github.com/masesgroup/retrieve-changed-files and we solved the issue. We updated the name to be able to publish the action on marketplace too.
Until now it is still in testing phase on our public repositories (https://github.com/masesgroup/JNet, https://github.com/masesgroup/KNet), however the action masesgroup/retrieve-changed-files@v2 seems to solve the issue while maintains the behavior.
