Release 0.19.0 (#7799)

### Next steps
- Test the release
- If this is an 'alpha' release, you can just merge the pull request.
- Otherwise:
  - For any added commits, run the release workflow in 'rc' mode again
- After testing, _ensure that this PR is mergeable to _, then run the
release workflow in 'release' mode
- Once the final release workflow finishes it will create a GitHub
release for you. Then:
    - [x] Sanity check the build artifacts:
      - [x] pip install: does it install and run?
      - [x] cargo install of cli tool: does it install and run?
      - [x] C++ SDK zip: does it contain rerun_c for all platforms?
- [x] Populate the release with the changelog and a nice header
video/picture, check , then click .
- [x] Update the [google colab
notebooks](https://drive.google.com/drive/folders/0AC0q24MFKh3fUk9PVA)
to install this version and re-execute the notebook.

A few hours after the GitHub release is created,  will create a
[conda feedstock
PR](https://github.com/conda-forge/rerun-sdk-feedstock/pulls).
Make sure Jeremy is on top of it!

- [x] Tests
  - [x] Windows
  - [x] Linux
