Feature description

Currently dependabot enforces the dependabot configuration file to reside in one of two locations - .github/dependabot.{yml/yaml}.

I have use case where, due to repository size/complexity, I am looking to consolidate a number of automation-related tasks and configurations into a single Automation folder. This will help to keep my repository clean and tidy, with a clear seperation of concerns for automated config/scripts.

This file specifically is causing the block.

dependabot-core/common/lib/dependabot/config/file_fetcher.rb

Line 9 in ef20a02

CONFIG_FILE_PATHS = %w(.github/dependabot.yml .github/dependabot.yaml).freeze

I propose that the file be modified to have the file paths passed in via config, and an option added to allow a custom file location for the configuration to be added.
