Pretty-simple "find dependency updates" helper
Browse files Browse the repository at this point in the history
While building github.com/cadence-workflow/cadence-go-client/pull/1060, I realized I kinda missed the out-of-date warnings.
So here's something kinda similar.

It may be worth adding e.g. a "nothing > 100 days" check to `make lint` and/or CI?
Otherwise I tend to see dependencies go un-upgraded for huge lengths of time.
