Disable auto-close in search (#35005)

Currently if you type `\(`, it auto-closes to `\()` which is broken.

It's arguably nice that if you type `(` it auto-closes to `()`, but I am
much more likely to be looking for a function call `name\(` than to be
starting a group in search.

Release Notes:

- search: Regex search will no longer try to close parenthesis
automatically.
