Pin protobuf version for TF dependency tests

[jrmccluskey]

The Tensorflow dependency test running against TensorFlow 2.12 was failing as the test environment was separately installing protobuf 5.x. This ensures that an appropriate protobuf version is installed before installing beam deps.

Fresh run of the workflow against this branch is running at https://github.com/apache/beam/actions/runs/11258372012 - there are some pandas/numpy failures that are unrelated.

hmm, this is working locally but the protobuf version is getting clobbered when the action runs. weird.

for the record this is still not working, the protobuf version keeps being upgraded. current idea is to just disable these tests so we get signal from the rest of the suite while I figure out how to fix them

Okay, got a clean run on https://github.com/apache/beam/actions/runs/11298052670/job/31426200604 (the numpy failures have been fixed on master)

PTAL at lint errors

[jrmccluskey]

I don't understand how there's a linting failure when the only file changed isn't python and doesn't get linted...
