psc-ide-use-npm-bin stops working after upgrading to npm@9.x.x

[boygao1992]

Apparently they removed npm bin command since 9.0.0-pre.0 so psc-ide-use-npm-bin needs a different strategy to local the purs binary.

feat: remove npm bin #5459

BREAKING CHANGE: this removes the npm bin command

The output of this command is misleading and incomplete. The .bin
resolution of npm is much more nuanced than this command implies, and
the output of npm bin is not something end users should be dealing
with. npm itself is responsible for running the bin entries of
modules, with the exception of global bins, which end up in the same
folder as node itself, presumably already in a user's path since they
can run node.
