Choose a name for the form builder library

[miguelgrc]

Ideas:

• jsonschema-form-builder (long and boring, but self-explanatory)
• FormPulse
• MosaicForm (the editor works by moving and putting pieces together so it reminds me of that)
• Mosaik (if we want to drop the Form part, there is a JS framework named Mosaic already, so we can write it with a k :man_shrugging: )
• Fomu (form in japanese, short and concise, but someone had the same idea and there's already a package with that name in npm - we can still have it as @cern-sis/fomu)
• FORMule (same as above, but we can have a mule as logo and the slogan can be "it does the heavy work for you")
