conda does not answer automatically yes

Hi

in my case the installation stopped at this step
`conda create --name alphafold python==3.8`
because some yes/no questions were asked.

I fixed it this way:
```
     conda create --name alphafold python==3.8
     conda update -n base conda
```
become
```
     conda create -y --name alphafold python==3.8
     conda update -y -n base conda
```
