Get secrets (Docker login credentials) in `build-quesma-docker-image.…

…yml` (#868)

A hot fix after 0c220f9. After it was
merged, the reusable workflow ("child workflow") doesn't get the secrets
(docker credentials) by default, resulting in a job failure.

Fix the issue by specifying the needed secrets for the reusable
workflow.

The secrets are not required if `PUSH` doesn't happen and only the
`nightly-docker-build-and-push.yml` workflow actually passes those
secrets.
