Fix docs: formview -> readonly

[kfina-planxy]

Steps to reproduce

In a form.blade.view do:

<x-twill::input
        name="myfield"
        :readonly="true"
    />

as docs state the field name is "readonly"

Expected result

Field is readonly.

Actual result

Field is NOT readonly.

Solution

Change readonly to read-only:

<x-twill::input
        name="myfield"
        :read-only="true"
    />

Please update the docs to show that for "@formview" the field is named "read-only" instead of "readonly" or at least add it to the code example with "read-only".
