Single line Portable Text input + improvements and bugfixes

• Adds a boolean oneLine option to the block schema type which, when set to true, will render the Portable Text Editor as a single line input

defineField({
      type: 'array',
      name: 'oneLineEditor',
      title: 'One-Line Editor',
      description: 'This editor is restricted to one line of text',
      of: [
        defineArrayMember({
          type: 'block',
+         options: {
+           oneLine: true,
+         },
        }),
      ],
   }),
