Bumps esinstall's rollup version to fix lit-html error (#1579)

Fixes an error in esinstall with the lit-html library caused by the commonjs plugin + rollup version. In rollup v2.23 - v2.28.2 the transform hook would return undefined instead on the transformed library code. This error was fixed in the following pull: rollup/rollup@1ad8289#diff-58036290d63f45dcebfa80ddeeb5877187a613f7cdb28e9a5482324f632c14ad
