Configurable `jsdom` directory in `JSDOMNodeJSEnv.Config`

[ptrdom]

Would a PR to add this setting be accepted? Seems like it would definitely be useful and I cannot think of a simple workaround for it, scalajs-bundler even has its own copy of JSDOMNodeJSEnv to do it - https://github.com/scalacenter/scalajs-bundler/blob/main/sbt-scalajs-bundler/src/main/scala/scalajsbundler/JSDOMNodeJSEnv.scala.

Isn't it enough to set the NODE_PATH env variable for this?

@gzm0 This indeed works, env variables are configurable in the current Config implementation. Thank you!
