Fix Style/TernaryParentheses offenses
What does this MR do?
The cop checks for unneeded parentheses for ternary operators. It would be cool to have it enabled for all files.
# bad
foo = (bar?) ? a : b
foo = (bar.baz?) ? a : b
foo = (bar && baz) ? a : b
# good
foo = bar? ? a : b
foo = bar.baz? ? a : b
foo = bar && baz ? a : b
