Subject: [PATCH] Tokens: add `T_FN` to `$parenthesisOpeners` array

While as per [@gsherwood's comment](https://github.com/squizlabs/PHP_CodeSniffer/issues/2523#issuecomment-552235605) in 2523, arrow functions are not set up as scope openers, I think adding them to the `Tokens::$parenthesisOpeners` array would be justified.

I'm also wondering if the token should be added to the `Tokens::$weightings` array ?
