Run tests in the appropriate extra dependencies.

[laserprec]

Description

Our recommender package has several extra dependencies to address the different compute environments: recommender[spark,gpu,example,dev]. We should run our tests against the specific extra dependency so we can ensure users of the library would have minimum problems installing these extra dependencies.

Expected behavior with the suggested feature

For example:

• A user pip install recommenders[gpu, examples] should be able to run recommender utilities tested by pytest -m "gpu and notebooks and not spark
