Reconsider how solution-level items are handled

[MikeEvansLarah]

Currently we are using the project-level NuGet package to handle injecting items in at the solution-level (such as .editorconfig).

This is not a good match because it is a project-level solution to a solution-level concern.

Could we use some of GitOps based processes for this? For example, detecting new repos and issuing a PR with the relevant code artefacts we think are necessary (.editorconfig, documentation snippets, etc.)
