Command for updating all deps at once to latest

[bwplotka]

@kishaningithubi mentioned a good feature request in #135 (comment)

would like to have a bingo get -u option similar to go get -u to upgrade all my dependencies using a single command

In the meantime, I use this shell script:

#!/bin/bash

bingo list \
  | sed 1,2d \
  | awk '{print $3}' \
  | sed s/@.\*/@latest/ \
  | xargs -n1 bingo get

This largely works but failed to do the upgrade for oapi-codegen when it moved repositories. Kind of a huge ask, but adding that logic into the tool would help but maybe a new ticket type for folks to note when they had to do an upgrade like this.

Also, as an aside, go get -u plus renovatebot have done a great job of keeping our projects up to date. That script above has done a good job keeping our tooling up to date as well. So thanks for bingo, it's saved a bunch of errors and grunt work.
