Question: Is "i" tag supported as Custom Icon?

Hi there.

I have seen that you can actually define a custom icon with the following syntax:

<Button icon={() => <i className="pi pi-times" />}/>

See the forked example:
https://stackblitz.com/edit/awdxtv-ltawe4?file=src%2FApp.jsx

However, that syntax is actually not listed in the Custom Icons page.

Is this syntax actually supported?

If so:

• I guess the {...options.iconProps} (props injections) is actually not needed (it was not working with them)?

• Would it make sense to update the documentation to include that syntax?

Thanks in advance!
