Prioritize "Use Type Signature" action when available

Hey folks! Amazing job on this project! Really appreciate how wonderful this tool is 😄

The LSP client I'm using offers a "quick-fix" binding; which AFAICT just executes the first "code action" related to your cursor.

The issue I'm having relates to type holes;

E.g. If I write the binding:

```haskell
thing :: _
thing = 'a'
```

If I have my cursor on the type hole and run "quick-fix" in the Language server it executes the FIRST code action, which in my case seems to always be `Add PartialTypeSignatures`; when what I (and probably most folks) **always** want is the `Use type signature: '(Char)'` option (which shows up second in the list if I list them all).

I'm not sure if it's possible to control the ordering of code-action suggestions, but if it is It'd be great if "Use type signature" would always come first if available 😄
