typo in depends action

[infotroph]

Description

Fixes a typo in an update that I meant to push as a separate PR but added to #3346 by mistake 🙈.

@robkooper FYI:

• With this change, we're now building the Depends image every push for R{4.1, 4.2, 4.4}, and once a week for R{4.3, devel}. I plan to move 4.1 to weekly once we've finished bumping the supported version past it.
• Note that the Rdevel image is built from a Rocker image that's currently out of date, but I propose to leave it configured to be ready when the Rocker folks get their build unstuck.
• Once the depends images are all building, next step is to change the Actions workflows to test / build with the versions we want. I propose to wait until our current Ed2-git docker build issues are resolved before tackling this step.
