ci(zapier): commit .zapierapprc so CI can push to the linked app

`zapier push` failed in CI with "project hasn't been associated with an
existing integration" because .zapierapprc was git-ignored. It holds the
app id/key (identifiers, not secrets), so commit it. Clarify in .gitignore
that the deploy key lives only in ~/.zapierrc / the CI secret.
