Use available clang-format version for Ubuntu 22

[Ryanf55]

Purpose

ROS2 (on humble) comes with clang-format 14, but the scripts hard code clang-format 6. You can't install it in Ubuntu 22. Thus, it's time to migrate up a few versions.

$ sudo apt install clang-format-6.0

E: Unable to locate package clang-format-6.0
E: Couldn't find any package by glob 'clang-format-6.0'

Risk

Note - running version 14 results in the following diff (small):

Code style check failed, please run clang-format (e.g. with scripts/fix_code_style.sh)

I've applied the diff, and we now enfoce the same version of clang that is installed on Ubuntu 22.

Thanks for fixing this!

Was meaning to do this for a while now.

Would be great if you could rebase?

Done! Conflicts are resolved.

@Ryanf55 Any ideas for the build failures?

Oops, yep. I'll put it in draft and re-request review when it's fixed.

[Ryanf55]

Ready for final review. Let's try to get this in soon to fix all the style problems and enforce clean diffs after this.
