I guess we don't have to mention the minimum supported version (and even the introduced version) anymore as the contributors/users now have to use the LLVM 14 or later anyway and the format version 6 is generally available there.

The Rust compiler will automatically use the most up-to-date coverage mapping format
version that is compatible with the compiler's built-in version of LLVM.
