[MOB-3026] - Snapshot Testing Improvements

[d4r1091]

MOB-3026

Context

We want to introduce a series of improvements to reduce the CI time and improve test reliability.

Approach

• Overall improvement to the script
• Aggregates intuitively the device against which run the maximum tests possible
• In case of the need for a specific device, the runsOn overrides the default device and executes a dedicated build (useful for iPad-specific tests for instance that will produce a dedicated UI)
• Better validation and safe checks for the script
• introduced the possibility to intuitively select "all portrait" devices by simply passing ["all" "portrait"] as part of the devices list for a certain test class
• Updated iPhone devices removing the 14 (based on the 13) and adding the iPhone 15 from an opened PR in the Snapshot Testing library.

Next Steps? Have a dedicated branch for storing Snapshots. Ticket incoming 🎟️ .

The change is too big because of the newer snapshots. To review the files feel free to check the newer script and the newer configuration.

Looks like the first one linked did not run the snapshot tests at all, apparently because there was no version update, probably you had already re-introduced the correct versioning logic then?

I found this older one (https://github.com/ecosia/ios-browser/actions/runs/11825657659) which seems like what you want, still a huge improvement from 1h to 18min 🎉 👏

I've looked into the new script and the new configuration files and they look good 🙌

The performance improvement is huge 👏 🎉

Can't look into much else due to the change size, but from my side all good to go ✅
