Updated semantic-ui theme to use new @rjsf/utils and @rjsf/validator

- Bumped the main `package.json` to use the latest version of `Typescript`
- Updated `package*.json` to add `@rjsf/utils` to dev and peer dependencies and `@rjsf/validator-ajv6` to dev dependencies
  - Also, Removed a bunch of packages that were never used since the conversion to `tsdx`
  - Finally, bumped most of the dev dependencies that made sense to the latest version, except for those that cause breaking tests
- Updated all uses of non-schema utilities methods to `@rjsf/utils` and switched to using `registry.schemaUtils.XXX()` for those schema-based utilities
- Updated the import of `getDefaultRegistry()` to be directly from `@rjsf/core`
- Modified `SelectWidget` to use the new `processSelectValue()` function from `@rjsf/utils`
- Updated the tests to import the `validator` from `@rjsf/validator` to pass to the `Form`
  - Also updated the snapshots via the `test:update` script to deal with the little differences from the conversion
