opentelemetry-test-utils: skip installing grpc exporter only on Pypy

[xrmx]

Description

Builds on windows takes <1 minute on CPython, so skip only installing grpc on PyPy that is both flake and slow to install the dependencies. Hopefully it's enough to make dependabot happy again.

Thanks @emdneto for the help.

Uhm looks like this does not work as expected since we're installing grpc on windows and on pypy, said that since it looks like grpc is installed without issues we may just update this to drop on pypy and see if that'll make dependabot happy.

[emdneto]

what if we use the uv pip compile --python 3.10 --universal ... to generate the requirements.txt? It should solve the grpcio installation issues:

uv pip compile --python 3.10 --resolution lowest --universal tests/opentelemetry-test-utils/test-requirements.in -o tests/opentelemetry-test-utils/test-requirements.txt

See my last comment, on windows the test-utils job takes < 1 minute even if we install the grpc exporter so that's not a problem anymore. So I'll give it a try with just skipping pypy and see if dependabot is happy again before introducing another step to build these.
