ci: Fix auto publishing to Docker & Electron (#488)

As seen from #484, we don't automatically publish to Docker and Electron
targets. The reason for this is we have an strict `inputs.docker` and
`inputs.electron` check, assuming they will have a default value of
`true`. That said the `input` context only gets populated on a manually
triggered workflow, hence these jobs get skipped on auto publish
actions. This PR should fix the issue by replacing it with an explicit
`!= false` check, so it becomes `true` if the value is `null` or
`undefined`.
