Fix empty message in newer Sublime Text 4 versions

[dsego]

The new_file.insert method was misusing the edit parameter. Instead we can invoke a command to append text in the newly created window.

Context:

The edit parameter is not for new_file but for self.view.

Build 4158 https://www.sublimetext.com/dev

• API: Fixed crash when an edit token is passed to the wrong view

API Docs: https://www.sublimetext.com/docs/api_reference.html#sublime.Edit

Edit objects are passed to TextCommands, and can not be created by the user. Using an invalid Edit object, or an Edit object from a different View, will cause the functions that require them to fail.

My report on Sublime Text bug tracker: https://github.com/sublimehq/sublime_text/issues/6177

Closes issue #25

This fix works for me using the latest GitCommitMsg in Sublime Text Build 4166. Thanks @dsego !
