Update the guide to be compatible with the current version of
libcamera, as well as sync the code snippets with [0].
Apart from libcamera related changes, `meson build` is replaced with
`meson setup build`, and direct `ninja` calls are replaced with
`meson compile -C build`. And update the code block languages where
appropriate.
