Addon Controls: Fix saving on Windows

[ghengeveld]

What I did

This fixes Save from Controls on Windows where some bad regular expression matching caused Node to hang. The issue was some missing escape characters which caused actual newlines to appear in the production bundle after transpilation, rather than \n literals. Escaping these characters resolves that problem.

ChatGPT suggested replacing .|\r\n|\r|\n with [\s|\S] which matches the same thing (anything) but in a more elegant and efficient manner.
