Add wheel release workflow

[codesue]

Description

This pull request adds:

• a workflow that builds and uploads a model-card-toolkit wheel on release and publishes it to PyPI and TestPyPI
• a workflow to cherry pick commits
• documentation on how to perform releases
• updates zlib archive location to prevent Bazel commands from failing with not found errors (see https://zlib.net/zlib-1.2.11.tar.gz Not Found bazelbuild/bazel#15136)

These workflows and release process were adapted from those in tfx-addons.

I tested the changes by triggering the workflow on pull request:

• successful job
• TestPyPI release history
• example notebook that uses the wheel produced by this workflow

@codesue thank you for the awesome PR! Since we can push every version only once to PyPI, let's the lining and testing steps to the PR.
@casassg has done magic over at TFX Addons. I think we can copy and adjust the entire .github folder for the steps:
https://github.com/tensorflow/tfx-addons/tree/main/.github

The repo contains the workflows for linting -> tests -> build package -> push to pypi

What do you think?

[casassg]

Indeed. However note that MCT requires a bit more complexity when it comes to building it's wheel. We may want to clean it after.

Also Sue for now, we may want to just add everything after https://github.com/tensorflow/tfx-addons/blob/18274a7ee395f51bb89490dce33885aa16b98446/.github/workflows/release.yml#L31 into the workflow

[casassg]

we can iterate on this

[codesue]

• Updated to include build steps for publishing the wheel to PyPI and test PyPI.
• Created Set up testing pre-commit hook #239.

@codesue This is very nit, so apologies. Do we need to the tfx-base image here?

[codesue]

This image was convenient because it has the right versions of the tools need to build the wheel, e.g. bazel. It's used to build tfx wheels, which have similar build steps.

Ah, perfect! Thank you for the explanation @codesue!
