ci(very_good_flutter_plugin): evaluate fluttium dependency

[marcossevilla]

Description

currently, the very_good_flutter_plugin template contains a workflow that triggers e2e tests with Fluttium, see here.

this tool hasn't been updated in a while, we should investigate if we should find another e2e tool or remove these steps in the workflow altogether.

Requirements

• All CI/CD checks are passing.
• There is no drop in the test coverage percentage.

@marcossevilla Patrol is likely the main alternative here, it's widely used, well-maintained and handles native platform features out of the box. Maestro is also a candidate since its syntax is similar to Fluttium, although it doesn’t have a dedicated Flutter package, it's a very known framework even outside Flutter
