Runtime error related to `pkg_resources`

Hello 😌

> MacOS 13.1 (M1)
> PyOxidizer 0.24.0 (using the default Python distribution for my platform, i.e. 3.10.9).

After a successful build, when trying to run the resulting executable I get:

```
Traceback (most recent call last):
File "runpy", line 196, in _run_module_as_main
File "runpy", line 86, in _run_code

File "pkg_resources", line 856, in _resolve_dist
pkg_resources.DistributionNotFound: The 'opentelemetry-sdk' distribution was not found and is required by the application
error: cargo run failed
```
The issue is in a 3rd-party package, `opentelemetry-exporter-otlp-proto-http`.

I've found #378 and #236 , read the "[Support for pkg_resources](https://pyoxidizer.readthedocs.io/en/stable/oxidized_importer_resource_files.html?highlight=pkg_resources#support-for-pkg-resources)" section in the docs, and I was under the impression that it should just work (or rather, I'm not sure what to poke to make it work).

I've created a [repo that reproduces the problem](https://github.com/tatablack/pyoxidizer-issues); it's possible to just clone it and run `pyoxidizer run` to see the error.

Any suggestions or documentation pointers? I'm just trying PyOxidizer for the first time, so I can't say that I've read *all* the docs 😅

Start by cloning the linked pyoxidizer-issues reproduction and running `pyoxidizer run`; compare the result with the documented “Support for pkg_resources” section and referenced issues #378 and #236. Done means determining whether this is a PyOxidizer packaging bug or a documentation/configuration gap, and recording the required guidance or change.
