UI Builder uses Sentence Case for it's Context Menu items when it should use Title Case

Steps to reproduce:

1. Open any Project
2. In the Project Browser create a UI Document Asset and open it in UI Builder
3. Add any Element to the Hierarchy and select it
4. Right click it in the Hierarchy and observe the bottom of the Context Menu
5. Click on the kebab menu icon next to any Inline Value or Attribute and observe the Context Menu
6. Create a Style Sheet, add a Selector and select it
7. Click on the kebab menu icon next to any Style and observe the Context Menu
8. Add a Variable to an Element or a Selector and right click in the Variables list and observe the Context Menu

Actual results:

UI Builder uses Sentence Case across it's various Context Menus:

• Hierarchy Context Menu's last item - "Add selector..."
• Variables List - "Extract to Global variable"
• Inlined Styles - "Set variable", "Set as inline value"
• Styles - "Set variable", "Set as value", "Unset all", "Open selector in IDE"
• Attributes - "Unset all"

Expected results: All Context menu items use Title Case as per Editor Design guidelines
