fix(subplot.{md,py,yaml}): run Subplot binaries from the source tree

This is akin to installing them to a directory in PATH. Instead of
doing that, we amend PATH so that the directory in the source tree
with the binaries are in there. This adds a "given an installed
subplot" step to every scenario that needs to run a Subplot binary.
