GH-50758: [CI][C++] Use LLVM 22 on Debian experimental (#50759)
### Rationale for this change
Fix #50758 - `llvm-toolchain-20` package was [removed from Debian
experimental on Jul
14](https://tracker.debian.org/news/1774937/removed-12018-1-from-experimental/),
so the nightly `test-debian-experimental-cpp-gcc-15` fails with `E: Unable to
locate package clang-20` / `llvm-20-dev`.
### What changes are included in this PR?
Update LLVM 20 to 22 on Debian experimental in `dev/tasks/tasks.yml`
### Are these changes tested?
Yes, built locally and verified via crossbow.
### Are there any user-facing changes?
No.
