Add Git: Delete action to run git rm command on the current document

[dmitrivMS]

Fixes #111767

Added Git: Delete command which operates on the currently opened editor and runs git rm on the file, then closes the editor (if it is not dirty).

Added git.confirmCommittedDelete setting (on by default) to turn off the confirmation.

NOTE Since public API has no way to add a checkbox to the confirmation dialog, the setting can only be turned off from the settings file/UI.

Pull request overview

This PR adds a new Git: Delete command that allows users to delete files from a Git repository using the git rm command, invoked from the currently open editor. The command includes safety checks to prevent accidental deletion of files with uncommitted changes and provides a confirmation dialog (configurable via the new git.confirmCommittedDelete setting).

Key changes:

• Implements the git.delete command that runs git rm on the current document and closes the editor if not dirty
• Adds a confirmation dialog with customizable setting git.confirmCommittedDelete (default: true)
• Validates that files have no uncommitted changes before allowing deletion
