Github Action Workflows now require Node.js version 16

[slaesch]

The most recent release of pocket-apps / action-setup-firebase is apparently designed to use Node.js version 14.6.2.

Github Action workflows currently consider any Action that uses a version of Node.js < 16 to be deprecated.

For that reason, the pocket-apps / action-setup-firebase Action is causing this warning to be displayed:

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: pocket-apps/action-setup-firebase@v2

Please update pocket-apps / action-setup-firebase and provide a release version 3 that supports Node.js version 16.
