IconButtonProps not being auto-generated

**Describe the bug**
The props table on the `IconButton` docs page is not being auto-generated. This is because `typedoc` does not generate the type data if `Omit` is used on a `type`. It is currently in their todo list for the next version. For now we will use a manually generated props table.
