Change instructions for local conda install

[padpadpadpad]

Hi everyone

I would prefer to change this myself, but cannot work out where the docs for antismash live (if at all) on GitHub.

On creating a local install, it currently says:

conda create -n antismash antismash
conda activate antismash
download-antismash-databases
conda deactivate

But think it would be useful to be:

conda create -n antismash -c bioconda antismash

As it increases the chances antismash will be found automatically.

Cheers
Dan
