Does Evergreen support Dependabot configuration for private registries?

[charliew33]

Is your feature request related to a problem?

When setting up dependabot.yml files I typically need to set up at least one private registry, depending on the ecosystems being used. Is there a way to configure Evergreen to include the private registry config in the deployed dependabot.yml files?

Describe the solution you'd like

Ideally I'd like to be able to configure that for particular ecosystems, Evergreen should include the private registry config in the dependabot.yml, for example for npm:

version: 2
registries:
  npm-npmjs:
    type: npm-registry
    url: https://registry.npmjs.org
    username: octocat
    password: ${{secrets.MY_NPM_PASSWORD}}

updates:
  - package-ecosystem: "npm"
    directory: "/"
    registries:
      - npm-npmjs
    schedule:
      interval: "weekly"
