engine node version 18 not supported

[falopez10]

When adding the engines.node value as 18, github actions throws the following error:

Error: package.json in functions directory has an engines field which is unsupported. Valid choices are: {"node": "10"}, {"node":"12"}, and {"node":"14"}.

Deploys to runtimes below Node.js 10 are now disabled in the Firebase CLI. Existing Node.js 8 functions will stop executing on 2021-03-15. Update existing functions to Node.js 10 or greater as soon as possible.

Notices that this doesn't happen when I deploy on my local machine.

The dockerfile is globally installing firebase-tools@10.7.0. firebase cli is weird in that it uses the node package to manage node versions instead of the globally installed version. Unfortunately, firebase-tools does not support node18 yet for some architectures like arm because the node package does not. Is your github action running on arm?

Alternatively, you can add the --ignore-engines flag to your arguments and it might get firebase-tools to not care about the version of node you are using.
