[Internal] refactored databricks_mws_permission_assignment to Go SDK (

#3831)

## Changes
- refactored `databricks_mws_permission_assignment` to Go SDK
- added `TestUcAccAssignGroupToWorkspace` to flaky tests

## Tests
<!-- 
How is this tested? Please see the checklist below and also describe any
other relevant tests
-->

- [x] `make test` run locally
- [x] covered with integration tests in `internal/acceptance`
- [ ] relevant acceptance tests are passing
- [x] using Go SDK
