update AlphaFold 3 docs

[fizwit]

model and parameter data should be bind mounted

[dtenenba]

This is not needed because we already have

--model_dir=$MODEL_PATH

and

$MODEL_PATH is /root/public_databases/parameter_models/.

Also, the syntax is wrong on the line you added, the = should be a :, but again, this is not needed.

[fizwit]

lets use the real path to the parameter data: export MODEL_PATH=/shared/biodata/alphafold3/parameter_models

fixed
--bind $MODEL_PATH:/root/models \

[dtenenba]

I tried this and got:

FileNotFoundError: [Errno 2] No such file or directory: '/shared/biodata/alphafold3/parameter_models'

Inside the container /shared/biodata is not visible.

I ran the existing script and it worked. I just changed BASE to a directory that had an input json file and an output/ directory.
