Unpin numba<0.58 (#15031)

I think unpinning `numba` in the conda recipe was just missed in #14616.

I discovered this issue [trying to build the `24.02` release](https://github.com/rapidsai/cudf/actions/runs/7878153691/job/21496377912#step:7:1674).

PRs & nightly builds are working because the `rapidsai-nightly` channel has an older version of `pynvjitlink` that supported `numba>=0.57` whereas the `rapidsai` channel only has the latest version which pins to `numba>=0.58`.
