Fix 2280 by moving the bootstrap 3 marker classes out of SchemaField

Fixed #2280 by moving marker classes from `SchemaField` to `WrapIfAdditionalTemplate`
- In `@rjsf/utils`, updated `WrapIfAdditionalTemplateProps` to pick up the `hideError` and `rawErrors` props from `FieldTemplateProps`
- In `@rjsf/core`, updated `SchemaField` to move the `form-group` and `field` marker classes to the `WrapIfAdditionalTemplate`
  - Also moved the `field-error`, `has-error` and `has-danger` error marker classes
  - Updated the grid snapshot due to the change
- Updated the snapshots in other themes due to the removed marker classes
- Updated the `CHANGELOG_v6.md` and `v6x upgrade guide.md` to reflect these changes
