Currently, the GHA linux-cross-build for RISC-V would not continue and is simply skipped when this debootstrap for "sid" repos fails. (See [JDK-8326960](https://bugs.openjdk.org/browse/JDK-8326960) for more details). This is affecting GHA linux-cross-build for RISC-V for quite some time. As a result, we failed to catch some early build issues.

I find the most recent usable shapshot is https://snapshot.debian.org/archive/debian/20240228T034848Z/. We can switch back to more stable Debian repo once it graduates.

I generally skip most GHA related PRs as there are plenty of other reviewers on this mailing list with deeper GHA knowledge than I have, and it's not a focus for my current role at my employer. This patch was however small enough so I was comfortable approving it. 

Tagging me, or someone else, specifically in a PR, requesting a review with the intent of getting it quicker, will likely just have the opposite effect as it may deter other people from jumping in to review, thinking you already have some kind of agreement with the person being tagged.
