Migrate to Node.js 16

[m8mble]

First of all, thanks for this great action.

When using it (e.g. here), I lately started to see the following warnings:

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: seanmiddleditch/gha-setup-ninja

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/

It would be great to get a new release, that works both with the updated Node.js as well as without any warnings.
