With the meson test suites being reworked to be automatically generated,
rather than having to be hard-coded in the meson.build file, we need to
update our contributing guidelines to take account of this change.

NOTE: this patch contains only changes needed to bring the doc
up-to-date with the meson suite registration changes. I believe the doc
needs further general updates beyond this, but that is out of scope for
this patch.
