[Snackbar][base] Drop component prop

[nicolas-ot]

• I have followed (at least) the PR section of the contributing guide.

BREAKING CHANGE

part of #36679
It will be covered by codemod, see #36831

For Base UI components, the component prop value should be moved to slots.root:

<Snackbar
-  component="span"
+  slots={{ root: "span" }}
 />

If using TypeScript, you should add the custom component type as a generic on the TabsList component.

-<Snackbar
+<Snackbar<typeof CustomComponent>
   slots={{ root: CustomComponent }}
   customProp
 />
