Upgrade stack snapshot to use ghc-9.2.5 (#1621)

* upgrade stack snapshot to use ghc-9.2.5

* use lts-20.2

* Update alpine GHC Dockerfile to 9.2.5

We also build the Juvix runtime before the stack build in the
linux-static-binary workflow file.

* Add some documentation on how to build and deploy the alpine GHC image

* Docker documentation clarification.

+# The GHC alpine image
+
+We need this image to workaround an issue with the official GHC alpine binary,
+see https://gitlab.haskell.org/ghc/ghc/-/issues/20266
+
+We use this image to make static linux binaries.
+
+## Building the image
+
+The tag of the image should be prefixed by the location of the GitHub docker
+repository that you're pushing to. In this case the repository is `
+ghcr.io/paulcadman`.
+
+``` shell
+docker build -t ghcr.io/paulcadman/ghc-alpine:9.2.5 -f Dockerfile-ghc-alpine-9.2.5 .
+```
+
+## Authenticating with the GitHub Docker repository
+
+First create a classic personal access token with `repo` and `write:packages`
+permissions.
+
+Consult the GitHub documentation on how to do this:
+
+https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry#authenticating-to-the-container-registry
+
+Set the token to the variable `CR_PAT` and then authenticate:
+
+``` shell
+echo $CR_PAT | docker login ghcr.io -u USERNAME --password-stdin
+```
+
+NB: You do not substitue your username for `USERNAME` in the command above.
+
+## Testing the image
+
+``` shell
+docker run -it --rm ghcr.io/paulcadman/ghc-alpine:9.2.5
+```
+
+## Pushing the image
+
+``` shell
+docker push ghcr.io/paulcadman/ghc-alpine:9.2.5
+
+```
