Since BoTorchSampler was migrated to Optuna integration and isn't in the Optuna main repository anymore, what about removing BoTorchSampler? > @y0z

I think including BoTorchSampler in the list is OK.

Motivation
In the FAQ, a sampler that supports contraints was missing, i.e., GPSampler. See https://optuna.readthedocs.io/en/stable/reference/samplers/index.html for reference. This has been fixed.
Description of the changes
Add sampler to enumeration within answer in FAQ.
