This adds a migration to migrate existing alignment options to their
legacy counter parts (`start` -> `start-legacy`, `end` -> `end-legacy`,
`middle` -> `middle-legacy`).
With this change the legacy options don't show any align as active in
the Styles panel:
I think this is probably what we want.
### Change Type
- [x] `patch` — Bug Fix
### Test Plan
1. Use some old preview link to create Geo and Note shapes with old
alignment options. You can use this one:
https://examples-kzwtf68jr-tldraw.vercel.app/
2. Copy and paste these shapes over to staging. Nothing should change
visually.
3. Also try out exporting to svg (with both old and new alignment
options)
- [x] Unit Tests
- [ ] Webdriver tests
### Release Notes
- Add support for legacy alignment options.
