Dhruv Manilawala 540023262e Collect errors while building up the settings index (#12781)
## Summary

Related to https://github.com/astral-sh/ruff-vscode/issues/571, this PR
updates the settings index builder to trace all the errors it
encountered. Without this, there's no way for user to know that
something failed and some of the capability might not work as expected.
For example, in the linked PR, the settings were invalid which means
notebooks weren't included and there were no log messages for it.

## Test Plan

Create an invalid `ruff.toml` file:
```toml
[tool.ruff]
extend-exclude = ["*.ipynb"]
```

Logs:
```
2024-08-12 18:33:09.873 [info] [Trace - 6:33:09 PM]   12.217043000s ERROR ruff:main ruff_server::session::index::ruff_settings: Failed to parse /Users/dhruv/playground/ruff/pyproject.toml
```

Another way to trigger is to provide an invalid `cache-dir` value:
```toml
[tool.ruff]
cache-dir = "$UNKNOWN"
```

Same notification preview but different log message:
```

```

With multiple `pyproject.toml` file:
```
