Document ES|QL prettify keyboard shortcut

[Copilot]

The ES|QL editor gained a keyboard shortcut for prettifying queries that was missing from the docs. This updates the ES|QL keyboard shortcuts section to include the new shortcut.

• Docs update
  • Added cmd+i / ctrl+i entry for “Prettify query” in the ES|QL keyboard shortcuts table
  • Linked the “Prettify query” shortcut to the query formatting section on the same page
  • Noted the shortcut applies to stack 9.4+

Example:

| {kbd}`cmd+i` | {kbd}`ctrl+i` | [Prettify query](#_make_your_query_readable) {applies_to}`stack: ga 9.4+` |
