fix(rangeSlider): handles were blocked (#2849)

This was because rheostat (our preact version) was using incompatible
versions from ours (preact and preact-compat).

This PR makes sure that we are using the same exact version as the min.
for rhoestat in order to end up with the same dependencies when resolving
the dependencies.
