Configure GitHub Actions to build iOS app

[eecavanna]

There are some third-party actions that, after having skimmed its documentation, I think can be used to build an iOS app.

For example:

• https://github.com/sparkfabrik/ios-build-action (docs say "tested with Ionic")
  • Note: there's an Android counterpart by the same author: https://github.com/sparkfabrik/android-build-action (docs say "tested with Ionic")
• https://github.com/marketplace/actions/ios-build-action

I don't know what the gap is between what we have in our repo (given that our repo contains an Ionic app, as opposed to an iOS app in isolation), and what this action "expects."

I also don't plan to pursue this immediately, as I have not build the iOS app locally yet and want to get comfortable with that process before setting up an automatic version of it.

I do think it could come in handy down the road, though.
