sorting unsorted quantiles

Checklist

Please:

• [X] Make sure this PR is against "dev", not "main".
• [X] Request a review from one of the current epipredict main reviewers: dajmcdon.
• [ ] Make sure to bump the version number in DESCRIPTION and NEWS.md. Always increment the patch version number (the third number), unless you are making a release PR from dev to main, in which case increment the minor version number (the second number).
• [ ] Describe changes made in NEWS.md, making sure breaking changes (backwards-incompatible changes to the documented interface) are noted. Collect the changes under the next release number (e.g. if you are on 0.7.2, then write your changes under the 0.8 heading).
• [ ] Consider pinning the epiprocess version in the DESCRIPTION file if
  • You anticipate breaking changes in epiprocess soon
  • You want to co-develop features in epipredict and epiprocess

Change explanations for reviewer

The quantile sorting issue continues to crop up somehow.

I'm going to close this. The problem is upstream: requested quantiles must be passed to rand_forest("regression") |> set_engine("grf_quantiles", quantiles = c(.01, .025, 1:19 / 20, .975, .99)).
