## Summary
On `main`, red-knot:
- Considers `P | Q` equivalent to `Q | P`
- Considered `tuple[P | Q]` equivalent to `tuple[Q | P]`
- Considers `tuple[P | tuple[P | Q]]` equivalent to `tuple[tuple[Q | P]
| P]`
- ‼️ Does _not_ consider `tuple[tuple[P | Q]]` equivalent to
`tuple[tuple[Q | P]]`
The key difference for the last one of these is that the union appears
inside a tuple that is directly nested inside another tuple.
This PR fixes this so that differently ordered unions are considered
equivalent even when they appear inside arbitrarily nested tuple types.
## Test Plan
- Added mdtests that fails on `main`
- Checked that all property tests continue to pass with this PR
