goroot alias directory somehow?

In Bazel 8.0, the path separator will change from `~` to `+`. (See the [7.3.0 release notes](https://github.com/bazelbuild/bazel/releases/tag/7.3.0) and [associated PR](https://github.com/bazelbuild/bazel/issues/23127))

That means the documentation for various IDE settings (and I assume other bits?) will have to change. It would be nice to have some prettier, more stable alias for the GOROOT and similar things needed. I'm not sure how much power bazel provides for this, though, so it's possible this ticket just needs to be closed or turned into a update-the-docs-when-change-lands ticket.

Read the referenced Bazel 7.3.0 release notes and associated issue 23127 first, then inspect the documentation for IDE settings that uses the `~` separator. Determine whether a stable GOROOT alias is supported; done means either documenting the required Bazel 8.0 update or recording that the alias is not feasible.
