Dependabot: Update syntax for ignore dependency names. (#512)

Dependabot created a lot of update PRs for mu_devops actions. This was
tracked back to dependabot configuration needing its syntax tweaked.


https://docs.github.com/en/code-security/dependabot/working-with-dependabot/dependabot-options-reference#ignore--

Relevant section:

dependency-name | Ignore updates for dependencies with matching names,
optionally using * to match zero or more characters.

This week was the first time dependabot created individual PRs for the
mu_devops actions.

I suspect this has always been an issue. I am not aware of a case where
mu_devops was tagged and there way a week's gap between version.njk
being updated and file sync run.
