Bernhard Kirchen 2f4eef47e9 webapp: autocompile script needs to run yarn within webapp dir
we need to change the working directory to the webapp directory such
that corepack installs and uses the expected version of yarn. otherwise,
corepack installs a copy of yarn into the repository root directory.
