Snippets/completions: Add parentheses to functions on commit-character (tab, return, whichever is in current settings)

Is your feature request related to a problem? Please describe.
Not exactly a problem.

Describe the solution you'd like
Just a minor QOL suggestion that could shed a smidge of time off typing out code. It would be cool to have intellisense completions (on commit key) of functions add parentheses after the function name and place the cursor inside the parentheses.

Describe alternatives you've considered
I add the parentheses myself.
