Install h5py in Versioning job for TRO regen (#285)

scripts/generate_trace_tros.py imports policyengine.core.release_manifest,
which transitively imports policyengine.core.scoping_strategy which
imports h5py. The Versioning job runs on a bare runner with only
`pip install -e .`, which doesn't include h5py (it's normally
brought in via the [us]/[uk]/[dev] extras). Add h5py to the install
line so the TRO regeneration step can import the module chain.
