Subject: [PATCH 1/2] fix(slack): don't send Slack msgs multiple times

One workflow gets triggered per label that was added. For example, in
"content" and "resources". Our if statement checked with `contains`
against the `issue.labels.*.name` array, which included both labels
already since these labels were created alongside the issue; opposed to
being added individually.

Instead, check that the label triggered this workflow is what we're
looking for.
