Release: bump version to 0.2.0 (#564)

## Summary

Follow-up to #558. Bumps the root `pyproject.toml` version from `0.1.0`
to `0.2.0` to trigger the new release workflow and cut the first
versioned release.

## Test plan

- [ ] On merge, confirm `v0.2.0` tag exists on origin pointing at the
merge commit
- [ ] GHCR + APHL ECR each have `index` / `ttc` / `augmentation` with
`:v0.2.0`, `:v0.2`, `:v0`, `:latest`
- [ ] GitHub Releases page shows `v0.2.0` published with auto-generated
PR notes
- [ ] Slack receives the release link
- [ ] `docker-image-push.yml` `build` job is skipped on the release
commit
