infra: use toml-cli to manually set version in github action

[kevinjqliu]

Which issue does this PR close?

• Closes #.

What changes are included in this PR?

See comment for context
Previously used cargo-edit but it does not allow setting version from 0.6.0 -> 0.6.0-rc1.

This PR changes the github action to use toml-cli to manually override and set the version in the binding/python/Cargo.toml so that we can build pre-release artifacts to push to pypi.

Are these changes tested?

Yes, similar to #1449

• downloaded wheels-sdist, verified correct version in PKG-INFO but not in Cargo.toml. I think this is fine
• downloaded wheels-ubuntu-latest-armv7l and verified the METADATA file

@Xuanwo can you double check this statement? I think its fine esp because since we only care that pypi parse the artifact as pre-release. But want to get a second opinion. :)
