Pin test tool versions in CI

[mthrok]

All the unittests jobs are failing due to import error related to protobuf and scipy.
This commit pins the versions of them to an older version.

protobuf

E   TypeError: Descriptors cannot not be created directly.
E   If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
E   If you cannot immediately regenerate your protos, some other possible workarounds are:
E    1. Downgrade the protobuf package to 3.20.x or lower.
E    2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

scipy (pypocketfft)

1.8.1 is causing issue.

LGTM. Please fix lint before merging.

[mthrok]

LGTM. Please fix lint before merging.

Let's follow up on that one. Lint is broken due to the discrepancy between OSS and fbcode, and we have not figured out what to do yet. (probably disabling it is the way)
