FormField triggers errors when it has null as a child

[kariwhitcomb]

Expected Behavior

We have code similar to this (without the explicit false)

<FormField>
        <TextInput />
        {false && <Text>foobar</Text>}
</FormField>

In v2.35.0 this would render fine with just the TextInput inside the form field

Actual Behavior

In v2.36.0 and v2.36.1 this code results in an error: 'Cannot read properties of null (reading 'props')'
It is failing around this line in FormField:

grommet/src/js/components/FormField/FormField.js

Line 220 in 74f3044

(child.props?.readOnly === true ||
