Added support to disable suggestion selection

[jack-lewin]

I've picked up https://github.com/signavio/react-mentions/pull/440 to try and get it merged.

This PR adds an optional disabled prop to suggestions.

If a suggestion is disabled, it...

• has a different style (reduced opacity, default cursor)
• is not selectable & has aria-disabled = true
• but still appears in the list

I've also...

• added tests for the SuggestionsOverlay component & new functionality
• updated the examples to disable one suggestion
• updated the README accordingly

If this lands, I'll make a separate PR to the DefinitelyTyped repo.

Feedback appreciated - cc @mastrix, @Sigrsig and @steffektif 🙏

Hi @Sigrsig & @steffektif, sorry for the nudge - are you still maintaining this project? If not, is there anyone else I should reach out to?
