canary shouldn't make changes on dry run

[laughedelic]

What Changed

Make more use of dry-run option in the code of the canary action.

Why

When running

auto shipit --dry-run --quiet

on a PR, it creates the comment 📦 Published PR as canary version: .... A workaround is to add --message false, but it shouldn't create any comments claiming that things are published when it's just a dry-run (to get the version value, btw).

I also noticed when running

auto canary --dry-run --quiet

locally, it resets my unstaged Git changes 🤯 This is a destructive bug.
