Use `git commit --verbose` when opening the external editor on a commit message

**Describe the solution you'd like**
Opening the external editor is actually not done by `git commit` command, so we may need to manually put the diff into the created COMMIT_EDITMSG file.

https://github.com/gitui-org/gitui/blob/e08d954573f2da5d66ace2822f439ee0b97ade34/src/popups/commit.rs#L160-L187

**Describe alternatives you've considered**
Or horner `commit.verbose` configuration variable. (#900)

**Additional context**
It would be useful to have a full diff in context when I edit commit messages in an external editor. This would allow me to benefit from completions and copilot, etc.



	pub fn show_editor(
	&mut self,
	changes: Vec<StatusItem>,
	) -> Result<()> {
	let file_path = sync::repo_dir(&self.repo.borrow())?
	.join("COMMIT_EDITMSG");

	{
	let mut file = File::create(&file_path)?;
	file.write_fmt(format_args!(
	"{}\n",
	self.input.get_text()
	))?;
	file.write_all(
	strings::commit_editor_msg(&self.key_config)
	.as_bytes(),
	)?;

	file.write_all(b"\n#\n# Changes to be committed:")?;

	for change in changes {
	let status_char =
	Self::item_status_char(change.status);
	let message =
	format!("\n#\t{status_char}: {}", change.path);
	file.write_all(message.as_bytes())?;
	}
	}
