Is this too much? 😅
We can just keep a simple format!("msg = ({}){}{}") instead.

So these probably should be omitted, right? But we don't have a general way to know if the inner expression needs parentheses, right?

Summary
This PR fixes the bug where the generated fix for
EM*rules would replace atriple-quoted (f-)string with a single-quoted (f-)string. This changes the
semantic of the string in case it contains a single-quoted string literal. This
is especially evident with f-strings where the expression could contain another
string within it. For example,
f"""normal {"another"} normal"""Test Plan
Add test case for triple-quoted string and update the snapshots.
