Dev TODOs

• [x] It seems that RJSF's component should have specific CSS class names, which needs a check also in the carbon theme.
• [x] Switch custom context to formContext or globalUISchema.
• [x] Fix styles in style tags.
• [x] More widgets.
• [ ] Figure out how to compile Sass files and distribute them to CSS.
• [ ] https://github.com/rjsf-team/react-jsonschema-form/issues/3918

• [ ] Update Tests.
• [ ] Update minor Version.
• [ ] Fix: Netlify CI failed with build with cache. Could not find a declaration file for module "@rjsf/utils"

Maybe we need OneOfFieldTemplate and AnyOfFieldTemplate, it's better than override a MultiSchemaField in custom theme. Also a SchemaFieldTemplate.

@YuJianghao How goes the work on this theme? You seemed to have stalled out. Do you need anything from us?
