Sebastian Poxhofer 183ee9caac fix(manager/rust-toolchain): report skipReason instead of dropping deps (#45144)
The manager emitted `logger.warn` four times during extraction and
returned `null` for content that is valid but not updatable. A
`rust-toolchain.toml` using `path` instead of `channel` is a legitimate
file, yet it failed schema validation and produced a maintainer-facing
warning.

Per the logging guidance in `docs/development/best-practices.md`, WARN
is consumed by metrics and error catching services, so it should not
fire for user content Renovate simply cannot update. The manager guide
also asks for a `skipReason` rather than silently dropping a dependency.

The schema now accepts an optional `channel` and an optional `path`, and
extraction reports:

- `invalid-version` when a channel cannot be parsed
- `path-dependency` when the file points at a local toolchain
- `unspecified-version` when neither field is set

`channel` takes precedence when both are present, since rustup rejects
that combination and `channel` is the actionable field.

Files that are not toolchain files at all still return `null`: TOML that
does not parse, TOML without a `[toolchain]` table, and legacy plain
text files that are empty or hold more than one line. The file pattern
matches any file named `rust-toolchain`, so these are treated as false
matches. All remaining logs are DEBUG.
