Fix the Draupnir Renovate annotations so updates are found again

The annotation read `depName=depName=ghcr.io/...`, so Renovate looked up a
package literally named `depName=ghcr.io/the-draupnir-project/draupnir` and found
nothing. Both Draupnir roles have been invisible to Renovate since v3.0.0 landed
in April, and the dependency dashboard has been reporting it as a repository
problem the whole time:

  Failed to look up docker package
  depName=ghcr.io/the-draupnir-project/draupnir: no-result

Checked every other annotation under roles/custom/ for the same shape; these two
were the only ones.
