Make FoldAtLevel commands discoverable in command palette (#39422)

Munish Mummadi and HactarCE created 3 weeks ago

## Description
Fixes #39376

Add individual FoldAtLevel1-9 actions so users can find fold commands in
the command palette while keeping existing keybindings.

Migrating user keymaps is necessary to have the keybinds show in the command palette.

Closes #39376 

### Changes
- `crates/editor/src/actions.rs` - Added FoldAtLevel1-9 action structs
- `crates/editor/src/editor.rs` - Implemented fold_at_level_1-9 handler
methods
- `crates/editor/src/element.rs` - Registered new actions
- `assets/keymaps/*.json` - Updated keybindings to use new individual
actions

### Other Approaches considered
- Adding #[serde(default)] to existing FoldAtLevel(u32) - wouldn't make
it discoverable
- Creating a single action with enumerated variants - idk about this
that well.

### Release Notes
Release Notes:
- Added Fold At Level 1-9 actions to the command palette
