feat: allow base button to be wrapped with tooltip

[sbeaury]

Problem

Solves #10223

Solution

Adds React.forwardRefso that MUI's tooltip can wrap RA custom button component

How To Test

This will now work

<Tooltip title="This is a button">
  <Button>My Button</Button>
</Tooltip>

A ButtonWithTooltip.tsx component could be added

I don't think this solves the linked issue, as other react-admin buttons don't forward the ref.

Also, can you add a story demonstrating this use case?

It does, the issue was specifically for custom buttons (so any custom button deriving from the custom Button like CreateButton, EditButton, etc will inherit from this added forwardRef). Added the example in a story.

CreateButton and other high-level buttons don't use forwardRef, so even if the lower-level Button does use it, your change doesn't allow a Tooltip wrapping a CreateButton, which is the issue pointed in #10223.
