[Bug]: .swcrc setting for sourceMaps not honored.

### What happened?

I set `sourceMaps: "inline"` in `.swcrc`. I compiled the code. No sourcemaps in the target.

### Version

Development (host) and target OS/architectures:
Ubuntu Linux / amd64

Output of `bazel --version`:
bazel 7.1.1

Version of the Aspect rules, or other relevant rules from your
`WORKSPACE` or `MODULE.bazel` file:

Language(s) and/or frameworks involved:

### How to reproduce

```shell
https://github.com/aspect-build/rules_swc/pull/282
```

### Any other information?

_No response_

Start with the reproduction linked in PR #282 and inspect the .swcrc sourceMaps setting used there. Run the Bazel build on Ubuntu with sourceMaps set to "inline", then compare the target output with the expected inline sourcemap behavior; done means the configured sourcemaps appear in the compiled target.
