ci: use custom directory in transformers workflow as HF home (#1268)

This commit introduces custom directory `.hf_home` for Transformers
tests via `HF_HOME` environment variable. Currently Transformers tests
populate this directory (with caches and whatever other stuff
Huggingface creates) with `28G` of data. Workflow is configured to
cleanup this directory after each run regardless of the test outcome.
