Adds update check and edit menu actions

Implements functionality to check for updates against GitHub releases.
It displays a prompt to download the latest version if a newer one is available.
If the 'requests' library is missing, it informs the user to install it.

Adds copy, select all and clear screen actions to the edit menu
for improved text editing within the application.
