[Bug]: Linter silently fails on parse error

### What happened?

`bazelisk lint` with a Python target and `ruff` configured should complain if `ruff.toml` is invalid TOML. When using `ruff` directly, invalid TOML results in an error like:

```
➜ pigweed git:(2432b18cb) ✗ ruff check
ruff failed
Cause: Failed to parse /usr/local/google/home/cramertj/src/pigweed/.ruff.toml
Cause: TOML parse error at line 16, column 11
|
16 | include = '\.pyi?$'
| ^^^^^^^^^
invalid type: string "\\.pyi?$", expected a sequence
```

But using `bazelisk lint` silently fails (yet says it has completed successfully!):

```
➜ pigweed git:(2432b18cb) ✗ bazelisk lint //pw_rpc/py/...
