Whenever we add a new repository that isn't a module/recipe/theme, we have to update a constant in order to tell the matrix generator not to add installer for it.
Instead of doing that, the generator just shouldn't try to add installer for those. Anything that isn't a recipe, a module, or a theme but which needs installer for its tests to run should explicitly add installer as a dev dependency.
I'm making this change instead of adding the new standards repo to the const.
[x] All commits are relevant to the purpose of the PR (e.g. no debug statements, unrelated refactoring, or arbitrary linting)
Small amounts of additional linting are usually okay, but if it makes it hard to concentrate on the relevant changes, ask for the unrelated changes to be reverted, and submitted as a separate PR.
