feat: [M3-8728] - Add Product Families to Create Menu dropdown (#11260)

## Description 📝
Add Product Families to the Create Menu Dropdown and display the desktop dropdown as 3 columns in a row; mobile will remain as a single column dropdown

Note: The Storage section was intentionally moved after Networking (different from the Side Nav Menu) since it has less items and can be in the same column as Databases. UX would prefer not to change the Side Nav order as it "reflects the info hierarchy from Ryan McEntee, that is also being used by TechDocs."

## Changes  🔄
- Add Product Families to Create Menu dropdown

Clean up 🧹 :
- Deleted unused nav components
- Renamed AddNewMenu to CreateMenu
- Variable renaming in PrimaryNav
- Updated unit test to use `userEvent` over `fireEvent`

## How to test 🧪

### Verification steps
- [ ] Open the create menu and ensure you can tab through the items. Clicking links still work as expected, etc
- [ ] Check mobile view

```
yarn test CreateMenu
```
