Revendoring all crates is broken

[criemen]

When trying to fix the CI on #2751, I ran the vendor.sh script, but it doesn't work on my computer:

 criemen@Corneliuss-MBP  ~/repos/rules_rust   label-fix ±  crate_universe/tools/vendor.sh

It's on macos, with bazel 7.2.1.

Sorry about this! #2768 should fix this issue, and #2769 consolidates our two "repin all the things" scripts into one.
