Some input types missing ability to add `description` to `Composition::Option`

[gabichuelas]

Looks like the library allows Composition::Option objects to be created with a description parameter (ref), but several input types are missing the ability to do so:

• StaticSelect
• MultiStaticSelect
• RadioButtons

While some others include it:

• Checkboxes

Happy to take care of this just wanted to put an issue up in case there was more context.

Hey @gabichuelas -- I think this is just an oversight!
