Replace HashableDict with frozendict.deepfreeze

[AdrianFreundQC]

Supersedes #27150.

HashableDict has been removed from conda_build in 24.7 and has been deprecated since 24.5.
This caused all PR CI builds to fail.
The deprecation message recommends using frozendict.deepfreeze instead.

I don't have permission to add the maintainance tag to this PR, so linter complains about changing non-recipe files.

Closes conda-forge/conda-forge-ci-setup-feedstock#332

Hi! This is the friendly automated conda-forge-linting service.

I was trying to look for recipes to lint for you, but couldn't find any.
Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

Hi! Thanks for your contribution to conda-forge.
We appreciate your effort in improving our project.
However, it looks like some changes were made outside the recipes directory.
To ensure everything runs smoothly, please make sure that recipes are only added to the recipes folder and no other files are changed.
Please make sure that any changes are reverted before you submit your pull request for review.

If these changes are intentional (and you aren't submitting a recipe), please attach a maintenance label to the PR.
Thanks!

CI confirmed working. Removed the test recipe again.
I don't have permission to add the maintainance tag to this PR, so linter complains about changing non-recipe files.
