Unclear instruction in activity

[stewartweiss]

The description of step 8 in the activity makes it seem as if the maintainer is supposed to merge the PR at that step. The intention though, is that this is an overview stating what will eventually happen in a later step. The language in step 8:
"Follow the Contribution Workflow to accomplish this goal. Maintainer, when asked to review the PR, accept and merge the PR."
would be clearer if it read:
Follow the Contribution Workflow to accomplish this goal. The Maintainer, will eventually be asked to review the PR, accept and merge the PR in a future step.
