[TASK] Fix npm copy of contrib packages

@lezer/common – in contrast to other @lezer modules,
is placed in dist/index.js instead of dist/index.es.js.
Therefore we add a distinct copy rule.

The sortablejs npm package recently changed to provide both,
a UMD bundle and a native ESM module.
As we actually failed to update the UMD bundle (due to a
rename of the build output filename in sortablejs),
we switch to the new ESM variant right away.

muuri failed to update because dashboardToEs6
was missing in the npmcopy concurrent target.
