Github Actions Deprecations

[Jay-Schneider]

Hi there,

Github Actions starts printing warnings for deprecations and this repository is affected. The main warning is concerned with the node version in use (currently 12), which should be updated to v16: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12

But there are also deprecations regarding the use of output and state manipulations: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

This may become evident after updating the node version.
