Add Ctrl+S / Cmd+S shortcut to save files in Theme and Plugin Editor

[Infinite-Null]

Trac Ticket: core 62080

Description

This PR introduces a keyboard shortcut (Ctrl+S / Cmd+S) for saving files directly within the Theme and Plugin Editor in WordPress. This enhancement is aimed at improving user experience and efficiency when editing code in the editor.

Changes Made

• Added JavaScript logic to listen for Ctrl+S or Cmd+S keypress events in the editor.
• Integrated the shortcut with the existing Update File functionality.
• Prevented the default browser save action to avoid conflicts.
