Changing this to draft until the gcc compiler can be updated in the pip devcontainer to 13 or higher.

@davidwendt can we close this now that #19371 is merged?

No. I was planning to merge this once we move to gcc 14.
Or rapidsai/devcontainers#534 this gets merged. Whichever is first.

JFYI at this point I'm probably going to punt the compiler update to 25.10 to avoid breaking anything mid burndown.

@davidwendt the conda and wheel builds have moved to gcc 14 and the devcontainers PR linked above is also merged, so you should be safe to open this PR for review now.
