{Build} Packaging - Align Gen2 Pilot Dataset deps and add wheel workflow

Summary:
Explanation:
`projectaria_gen2_pilot_dataset` declared its dependencies in `setup.py`
independently of the build graph, and both Rerun migrations (0.26.2, then
0.33.0) updated the build files while leaving `setup.py` behind. The published
package therefore pinned `rerun-notebook==0.22.1`, two major versions stale, and
omitted `numpy`, `tqdm` and `rerun-sdk` even though the data provider and the
viewer import all three directly.

- Declares every direct dependency in `install_requires`, using
  `rerun-sdk[notebook]==0.33.0` as `projectaria_tools` now does, so the SDK and
  the notebook widget cannot drift apart again.
- Adds a `projectaria-tools>=2.2.0` floor. The dependency was fully unpinned, so
  an environment with an older `projectaria-tools` already installed satisfied
  the requirement and was never upgraded, then failed at runtime on APIs the
  loader needs.
- Drops `extras_require`. Everything installs by default, so
  `pip install projectaria-gen2-pilot-dataset` no longer needs the `[all]`
  suffix; the README and the download docs are updated to match.
- Raises `python_requires` to `>=3.10` and drops the 3.8 / 3.9 classifiers, to
  match `projectaria_tools`.
- Reads the version from `version.txt` instead of hardcoding it in `setup.py`,
  as `projectaria_tools` does, and bumps it to `1.1.0a1`.
- Adds `.github/workflows/build-wheels-and-deploy.yml`: builds the sdist and
  wheel, runs `twine check`, installs the wheel and smoke tests the API and the
  console script, and can publish to test or prod PyPI from a manual dispatch.
  This package is pure Python, so one `py3-none-any` wheel replaces the
  `cibuildwheel` matrix that `projectaria_tools` needs for its native extension.
- Adds a minimal `pyproject.toml` for a deterministic build backend, and a
  `MANIFEST.in` so `version.txt` ships in the sdist. Without it, a wheel built
  from the sdist cannot resolve the version.

Reproducibility:
The workflow runs on pull requests and on a weekly schedule; publishing is gated
behind a manual dispatch. The install step resolves the full dependency set from
PyPI, so an unpublished or unsatisfiable pin fails the run.
