Downgrade missing sequence types warning to info

[lina-kim]

With the --verbose flag, a call to get-all generates the user warning "No paired-read sequences available for these accession IDs." As a user, I find the warning status confusing when nothing is wrong per se. Could we downgrade this status to INFO?

Sample command and output:

$ qiime fondue get-all --i-accession-ids toy-multi-ids.qza --p-email <> --p-n-jobs 4 --output-dir work-multi --verbose
