* Fix issue where helm index.yaml cannot be read

The result of this function call is destructured here: https://github.com/renovatebot/renovate/blob/d0d482155dbc8ec6d901105c246fb1542b6a3b00/lib/datasource/helm/index.ts#L65



If the return value is undefiend this causes an error, an empty object satisfies the RepoSource interface and can also be destructured without issue.

* update tests to match helm findSourceUrl behaviour

* feat(config): allow exporting async config (#13035)

module.exports can now be a function and it can be/return a Promise,
allowing the results of asynchronous operations to be used in the
configuration.

The discussion leading up to this PR in #13035 assumed that
module.exports had to be a plain object.

But this commit:

  commit 9aa97af5
  Author: Nejc Habjan <hab.nejc@gmail.com>
  Date:   Thu Dec 9 13:45:48 2021 +0100

      feat(config)!: parse JSON5/YAML self-hosted admin config (#12644)

      Adds support for alternative admin config file formats.

      BREAKING CHANGE: Renovate will now fail if RENOVATE_CONFIG_FILE is specified without a file extension

Had as an undocumented side effect, that it also handled transparenty
if module.exports was assigned a Promise. With that commit, the
promise will be await-ed so the resolved value is returned from
getConfig(). That was not the case before that commit.

So in this commit, configs that export functions are handled, and
test cases for both promises and functions have been added.
