Ignite --Version fails to work

[munsterlander]

Installed per the instructions:

flutter pub global activate ignite_cli

Built ignite_cli:ignite.
Installed executable ignite.
Activated ignite_cli 0.4.0.

Running ignite --version as per the pub.dev instructions throws:

ignite --version
$ ignite --version:
Unhandled exception:
FileSystemException: Cannot open file, path = 'C:\flutter\flutter\.pub-cache\global_packages\ignite_cli\bin\..\pubspec.yaml' (OS Error: The system cannot find the file specified.

Yet ignite create works fine.

This is an issue because we cannot access the pubpsec file when installed globally. See my issue here

If you run --version locally or on a non-global context, it would work.

We should either use this to lookup the pubspec file to get the version or generate the version at build-time like Melos does:
https://github.com/invertase/melos/blob/main/packages/melos/lib/src/command_runner.dart#L102
https://github.com/invertase/melos/blob/main/packages/melos/lib/version.g.dart

This should be fixed by #17
