Workspace migration v2 testing (#13136)

# Introduction
Introduced `EachTesting` pattern for the builder unit tests.
As always any suggestions are more than welcomed !


Still need to:
- [x] implem basic tests for field
- [x] create `get-flat-index-field-metadata.mock.ts`
- [x] Implement basic tests for index and index-fields
- [ ] Implem standard edges cases tests TDD style

## Misc
- was https://github.com/twentyhq/twenty/pull/13132 closed due to mess
to rebase on main
