Rationale for this change

Fix #50758 - llvm-toolchain-20 package was removed from Debian experimental on Jul 14, 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.
