Quiet conda install & remove conda solver (#1108)

Summary:
Fix the failed conda ci job which is caused by the dependencies conflicts of libmamba-solver
- remove the libmamba-solver and use the default solver instead

Also "quietly" execute `conda install` to disable progressbar, which pollutes the CircleCI logs
