[bitwarden] ability to fetch all fields from an item

Sometimes a projects has a lot of secrets (more than 10). And its
cumbersome to write $(kama secrets fetch ...) with a lot of field
names.

I want to be able to just fetch all the fields from a given item
 and then just use these with $(kamal extract NAME)
