[HANDS-ON BUG] Sample-factory numpy version mismatch.

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
thinc 8.3.6 requires numpy<3.0.0,>=2.0.0, but you have numpy 1.26.4 which is incompatible.
dopamine-rl 4.1.2 requires gymnasium>=1.0.0, but you have gymnasium 0.29.1 which is incompatible.

while performing !pip install sample-factory==2.1.1 in Google Colab.

Reproduce the reported !pip install sample-factory==2.1.1 command in Google Colab and inspect the resulting dependency resolution. Identify compatible versions for numpy and gymnasium, then verify that the installation completes without the reported conflicts.
