Require suggestions on UI changes

Hi Team,

I have made some UI changes for issue 6854
<https://github.com/pgadmin-org/pgadmin4/issues/6854>. I have added a
switch *Custom return type? *if enabled, an input text box will be
visible in which the user can provide their desired return type, and when
this switch is enabled return type select box will be disabled. This custom
return type input and switch will be visible only when creating a new
function.

Please provide your suggestions and feedback if these changes look okay to
you.

Regards,
Pravesh
