Added SkillTreeType enum and implemented dropdown selection in SkillTreeView

- Introduced a new `SkillTreeType` enum to represent different skill tree categories: General, Coding, Data, and Scrape/Synthesize.
- Extended the `SkillTreeType` enum to provide associated string values and JSON file names for each category.
- Refactored the `SkillTreeViewModel` to reload the skill tree data based on the selected category.
- Enhanced `SkillTreeView` by adding a positioned dropdown in the top-left corner to allow users to select and load different skill tree categories dynamically.
