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`

Registry aliases with variable defaults

Docker Compose files often use environment variables with default values:

services:
  foobar:
    image: ${CI_REGISTRY:-}image:1.0

To handle these variables, configure registry aliases with the default value syntax:

{
  "registryAliases": {
    "${CI_REGISTRY:-}": "my-registry.io"
  }
}

Both image reference formats work:

  • With a slash after the variable: ${CI_REGISTRY:-}/image:1.0
  • Without a slash after the variable: ${CI_REGISTRY:-}image:1.0

The alias value works with or without a trailing slash.
