Michael Kriese 312c380926 test(manager): cover the pre-commit warning switch and drop unreachable fallbacks (#46221)
* fix(util/http): make the legacy `headers` getter configurable

Every other property defined on `HttpError.prototype` in this file is
`configurable`, but `headers` was not. That makes the module fail with
`TypeError: Cannot redefine property: headers` whenever a test resets the
module registry and re-imports anything that pulls in `got.ts`.

* test(manager/pre-commit): cover the suppress-warning env var

`defaultConfig.prBodyNotes` drops the unsupported-manager warning when
`RENOVATE_X_SUPPRESS_PRE_COMMIT_WARNING` is set. Since the value is
computed at module load, the new spec resets the module registry and
re-imports the manager with the variable stubbed.

The `istanbul ignore next` on that arm is dropped because the branch is
now exercised.

* refactor(manager): remove unreachable fallbacks

Drop three defensive fallbacks that can never be taken:

- `docker-compose`: `config.services ?? config` always yields an object,
  so the `|| {}` guard behind it is dead
- `git-submodules`: `git.raw()` resolves to a string, so the `?? ''`
  never applies
- `maven`: the only site that builds a `MavenProp` always passes a
  `packageFile` string, so narrow the type and drop the `?? undefined`

Important note: The pre-commit manager is disabled by default and must be opted into through config. Renovate's approach to version updating is not fully aligned with pre-commit autoupdate and this has caused frustration for pre-commit's creator/maintainer. Attempts to work with the pre-commit project to fix these gaps have been rejected, so we have chosen to disable the manager by default indefinitely. Please do not contact the pre-commit project/maintainer about any Renovate-related topic. To view a list of open issues related to the pre-commit manager in Renovate, see the filtered list using the manager:pre-commit label.

When enabled, Renovate supports updating of Git dependencies within pre-commit configuration .pre-commit-config.yaml files or other YAML files that use the same format (via managerFilePatterns configuration). Updates are performed if the files follow the conventional format used in typical pre-commit files:

repos:
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v1.0.0
    hooks:
      - id: some-hook-id

To enable the pre-commit manager, add the following config:

{
  "pre-commit": {
    "enabled": true
  }
}

Alternatively, add :enablePreCommit to your extends array.

Additional Dependencies

Renovate has partial support for additional_dependencies, currently Go, Node.js and Python only.

You will need to explicitly add the language to your hooks with additional_dependencies to let Renovate know what kind of dependencies they are.
