[PATCH v2 1/1] .github/dependabot.yml: Enable dependabot

["Michael Kubacki" <mikuback@linux.microsoft.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

Enables dependabot in this repo so we can better alerted when
dependency updates are available.

This GitHub action will automatically create pull requests and
summarize the dependency details. Because it is a pull request,
the CI system will validate the dependency update in the pull
request.

Configures dependabot for:

1. PIP module updates
2. GitHub action updates

The maintainers/reviewers of the .github directory were added as
pull request reviewers so they can be notified when the pull request
is available.

    V2 Changes:
    
    1. Removed the "gitsubmodule" package ecosystem
    
    In the TianoCore Tools and CI Meeting, we decided
    to follow up in the future in enabling submodules
    on a case-by-case basis trying to move between
    release tags.
    
    For now, this change enables tracking of pip and
    GitHub action dependencies.
