Missing build dependencies for Fedora in CONTRIBUTION.md

[andrea3x]

I wasn't sure whether to post this as an issue or a discussion, I chose the latter because I found a solution and I don't have the full text of the error messages.
I'll leave it up to the project maintainers how to handle this problem.

Trying to build Spotube (last commit: 87a7854) in Fedora Linux 40 results in a few errors.

After following the guide in CONTRIBUTION.md, I only managed to build after:

• installing cmake (sudo dnf install cmake)
• installing ninja-build (sudo dnf install ninja-build)
• upgrading win32 project dependency making it a direct dependency (flutter pub add win32)
  • this was part of the error message: Error: Type 'UnmodifiableUint8ListView' not found.
  • the solution I found is based from this issue
• installing rustup (sudo dnf install rustup && rustup-init)
  • this was part of the error message: Cargokit BuildTool failed with error: rustup not found in PATH.
• upgrading media_kit and media_kit_libs_audio (flutter pub upgrade media_kit media_kit_libs_audio)
  • the error was: <command line>:1:9: error: macro name must be an identifier
  • the solution I found is based from this issue

After all these steps, I finally got the app launching.
I'm not into Flutter/Dart development, hence I probably made a mistake without meaning to, but if this guide can somehow improve the documentation, I'll be very happy!

This is a fantastic app, thanks!
