[llvm] [BOLT] Update Docker to use Ubuntu 24.04 (PR #99421)

[Tristan Ross via llvm-commits]

https://github.com/RossComputerGuy created https://github.com/llvm/llvm-project/pull/99421

Updates the Dockerfile to use Ubuntu 24.04 due to CMake wanting a newer version. Can be tested by trying to build the Docker image currently in main and then try building the Docker image in this PR.
