fix(lint/useShorthandFunctionType): add parens when needed

[Conaclos]

Summary

Fix #2595

Previously, the rule didn't add parentheses when they were needed.
It now adds parentheses when the function signature is inside an array, a union, or an intersection.

- type Union = { (): number } | string;
+ type Union = (() => number) | string;

Note: we should move the needs_parens utility from biome_js_formatter to biome_js_syntax.
It is not the first time we encounter this need.
Another possibility is to format the code fix with the formatter.
However, it is not actually possible?

Test Plan

I added non-regression tests.
