[Autocomplete] Simplify tooltip usage in options

I found an issue with the implementation of autocomplete. If you look at the PR you generate the props from the useAutocomplete hook and pass that directly to the li. This is an issue because #11601 you are passing disabled directly from that which doesn’t allow for the Tooltip workaround on the disabled elements here

I’ve already implemented this in #19235. I feel like this is a valid solution since you are currently able to change the 'ListBoxComponent = ul` to anything. You should have more control over the list item.

Also if you change the ListboxComponent to a div look at the HTML rendering. It renders invalid HTML and you can’t change the li to anything you need:

Heres a demo for the above screenshot:

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

The Tooltip isn’t opening for disabled items.

Expected Behavior 🤔

I expect Tooltip to render for disabled items. Using the workaround here the disabled items should render.

Steps to Reproduce 🕹

We need to be able to use the Tooltip to explain to our users why an item is disabled. See example below:

Steps:

1. Setup Autocomplete like above ^
2. Try to render a tooltip
3. The disabled items will not open the tooltip however the ones, not disabled will.

Context 🔦

We need to be able to use the Tooltip to explain to our users why an item is disabled.

Does anyone want to work on it? 😃

Looks like you already solved the problem and put the code, then what is remained? 😄

@ImanMahmoudinasab The hardest part is missing: to get it merged in the next branch. We would need a pull request, fix the tests, update the documentation, etc.
