ci: pass the correct account token for Snyk jobs

The secret in the project settings has a typo and is called `SYNK_TOKEN`
instead of `SNYK_TOKEN`. Changing the name of the secret does not seem
to be trivial; it needs to be deleted and re-created, which requires
obtaining a new token, somehow. Adopting the name with the typo in the
GitHub Workflow is easier.
