Update to a more recent version of clang-format in related job

Version 3.8 of clang-format is terribly old and difficult to install locally on even moderately recent versions of Ubuntu, requiring using docker for a simple CI-compliant local formatting check.

Some repositories may require some reformatting after this but it's so low effort that I'm not sure this requires a tick-tock cycle of adding an optional updated job before making it mandatory and dropping the old one.

Maybe it's a stupid question, but why are using PickNikRobotics clang-format file?

And not a file format generate by clang-format program?

clang-format -style=google -dump-config > .clang-format

Unfortunately clang-format-10 is not available on jammy.

I was able to install it anyway by setting adding

deb http://apt.llvm.org/focal/ llvm-toolchain-focal-10 main

to my sources list even though it is focal and my computer is jammy. I was then able to install clang-format-10 without breaking anything.

Alternatively, it seems to be packaged in PYPI, so you can probably install it quickly using pip or pipx.

It would be a good idea to include this info in the internal documentation. Volunteers?

Speaking of documentation, see #63.
