bitwarden [arg...]
bitwarden returns structured data retrieved from Bitwarden using
the Bitwarden CLI (bw). args are passed to bw get unchanged and the
output from bw get is parsed as JSON.
The output from bw get is cached so calling bitwarden multiple times with
the same arguments will only invoke bw once.
Example
username = {{ (bitwarden "item" "$ITEMID").login.username }}
password = {{ (bitwarden "item" "$ITEMID").login.password }}
