There is a minor [missing feature in dask-expr](dask/dask-expr#985). I suggest we relax this test a bit to handle both "legacy" and "new" DataFrame collections.

We should skip explicit-comms tests when dask-expr is active (for now).

Adding dask-expr support is part of #1311

Forward-merge branch-24.04 into branch-24.06 [skip ci]

It was brought to our attention that some links in our docs are broken, this change should fix those issues.

Currently, each time an error occurs the CI test script will only trap the error code an switch it to a code `1` which is not representative of the underlying error that occurred. This makes it a bit difficult to identify the source of the error, particularly in cases where the test times out (exit code `124`) and there's no summary in the log.

This change captures and prints the last error code upon exit, but also logs all errors that may have occurred throughout execution where they occurred, thus facilitating debugging.

Makes a few ~small~ changes to explicit-comms to support dask-expr.

EDIT: The changes are no longer "small".

Wireup may fail in UCX 1.16 in nodes with multiple NICs if TCP is used, thus skip those tests. UCX 1.17 will resolve the issue, and alternatively `UCX_PROTO_ENABLE=n` may be used in UCX 1.16 as well.

Just a small fix to the license name for our scanning tool and to [be consistent with other repositories](https://github.com/rapidsai/cudf/blob/branch-24.06/python/cudf/pyproject.toml#L23).

Proposes removing this project's build-time dependency on `tomli`.

It appears to no longer be necessary.

```shell
git grep tomli
```

## Notes for Reviewers

I originally noticed something similar in `ucx-py` (rapidsai/ucx-py#1042), then went searching for similar cases across RAPIDS.

I'm not sure why this project has a dependency on `tomli`, but I suspect it was related to the use of `versioneer` in this project's history. Reference: python-versioneer/python-versioneer#338 (comment)

This project doesn't use `versioneer` any more (#1204). I strongly suspect that the dependency on `tomli` can be removed.
