[REVIEW] FIX Install rapids pytest benchmark

[dillon-cullinan]

cuGraph pytests are dependent on this package to run properly, otherwise they run into the following error:

10:51:23 ERROR: usage: py.test [options] [file_or_dir] [file_or_dir] [...]
10:51:23 py.test: error: unrecognized arguments: --benchmark-gpu-disable

We do not use these arguments in the script, but they are added programmatically via cugraph's pytest.ini script in their repo, seen here: https://github.com/rapidsai/cugraph/blob/branch-21.06/python/pytest.ini

Good catch. One of the things we'll need to double-check here is that installing rapids-pytest-benchmark doesn't also install a different rmm version than the one that's initially provided by the environment. I believe Rick and I ran into this issue previously.

admin merging since CI doesn't run tests related to these changes anyway.
