Update three LDML files from SLDR

[papeh]

Quick Summary

CI-ready checklist

• Commit messages follow .github/commit-guidelines.md (subject ≤ 72 chars, no trailing punctuation; if body present, blank line then ≤ 80-char lines).
• No whitespace warnings locally:

  git fetch origin
  git log --check --pretty=format:"---% h% s" origin/<base>..
  git diff --check --cached

• Builds/tests pass locally (or I've run the CI-style build via Bash script or MSBuild).
• If this is core-developer AI-assisted work, I followed Docs/workflows/ai-pr-workflow.md and ran pr-preflight or the equivalent branch-readiness review before requesting review.
• For any Src/** folders touched, corresponding AGENTS.md files are updated or explicitly confirmed still accurate.

Really. Each time I run a localize build, the updated LDML files hang out in my list of files to stage until I revert them, which lasts until I run my next localize build. Thanks for understanding 😁

@jasonleenaylor, on second thought, perhaps we should remove them all and .gitignore them. SIL owns SLDR, so we'd get notice if it was going away, so we don't gain anything by caching these. It could be another download step in developer builds, and I could further consider consequences, but that may be the thing to do.
