Fix `workspace/reload` not importing dependencies without re-compilation

[Gedochao]

It actually doesn't do nothing, we should be supporting workspace/reload.

Line 80 in adca9c2

override def workspaceReload(): CompletableFuture[AnyRef] =

scala-cli/modules/build/src/main/scala/scala/build/bsp/BspImpl.scala

Line 557 in 01960be

private def onReload(): CompletableFuture[AnyRef] = {

After testing it a bit just now, it technically does work, but in this use case it's a bit wonky.

after adding a new directive/dependency in the code, workspace/reload doesn't seem to pick it up until the first re-compilation is triggered. It doesn't matter if it's from the command line, or if it's a re-run from IntelliJ and the re-run should go through BSP).

Not sure where's the bug, but it's worth investigating on our side. I'll create a ticket.
