all: remove reference to the nightly extension

The nightly is deprecated in favor of the new pre-release versions.
Clean up docs and references.

Use "Pre-release" instead of "Preview" in user-facing doc.
(We also use "insiders" or "preview" to refer to VS Code Pre-release
inside our code or project to distinguish from semver's prerelease,
but outside our project, "Pre-release extension" is the term to use)

For #1953

+for stable release).

+To install the pre-release version, use the drop-down list

 ### Release process
 
-The golang.go-nightly extension is released daily during weekdays, based on the latest commit to the master branch.
+> 🚧 Under construction 🚧
 
-(Note: the release process is currently in GH workflow. We are in process of moving it to a GCB workflow.)
+We are currently working on migrating the release process to the Go project's relui (golang.org/x/build/cmd/relui).
 
 * Dockerfile: defines the image containing tools and environments needed to build and test the extension. (e.g. Go, Node.js, jq, etc.)
 * build-ci-image.yaml: defines the workflow to build the container image used for extension testing and releasing.
-* release-nightly.yaml: defines the workflow that builds the nightly extension and runs tests. The built extension is pushed only after all tests pass.
+* release.yaml: defines the (soon-to-be-deprecated) workflow to build/publish the extension in GCB.
