Fix Kitsu Task type and status sync + tests

[johhnry]

Changelog Description

This PR mainly solves #72

• Fixed the short_name key to shortName
• Added the default icon task_alt for both task type and status
• Re ran unit tests and fixed database changes (new scope field in status, priority field on tasks)
• Use Poetry's new dependency groups for unit tests
• Use package-mode = false for unit tests because we don't need to treat the code as a package
• Fix codenamize dependency which was version ^1.2.4-dev.1 and didn't exist on Pip
• Add missing httpx dependency

Testing notes:

1. Create a new task type in Kitsu
2. Add it to your project
3. Create that task on an asset/shot
4. Make sure that you can browse the folders in the Launcher without errors and that it has the proper icon and shortName fields
5. You can do the same with task statuses
