fix: Pin packages in sdk/python/dev-requirements.txt

[kdestin]

Description

pip's version resolver (2020-resolver ?) will sometimes download many versions of a package to find one that satisfies installation constraints. This is usually just incurs a time cost since python packages are usually small, but this was problematic since packages like tensorflow, many nvidia packages, pytorch, etc... are 500MB+.

Pinning known compatible versions prevents pip from doing this search, and stops us from bumping up against the 14GB storage limit in Github Actions.
