Florian Müllner f250643385 style: Use space after catch
We are currently inconsistent with whether or not to put a space
after catch clauses. While the predominant style is to omit it,
that's inconsistent with the style we use for any other statement.
There's not really a good reason to stick with it, so switch to
the style gjs/eslint default to.
