Create Database_connections.qmd

[ehesch]

Hi @eroten - I'd like to add a vignette that walks through how to connect macs to council databases.

Thank you for writing this up, @ehesch! This highlights an important issue about communication and documentation. I have a couple points.

• Does the database connections section of the onboarding guide meet the instructional need?
  • in the function documentation for import_from_emissions() and import_from_gis(), accessible with ?, we link directly to the onboarding guide section on database connections, which in turn pulls from the si_onboarding guide.
  • If you didn't easily find the onboarding guide, how do we better direct users to it? Should there be a link in the README?

Also, props to you for trying out Quarto! Unfortunately, vignettes still need to be in RMarkdowns and require some extra formatting. You can create a new vignette with the helper function usethis::use_vignette("name"), which will get you set up with the appropriate YAML.

Closing this PR for now, pending ongoing discussions on database use cases.
