gitlab-ci: Refactor compilation of gen_ci
Flakify and document it, making it far less sensitive to the build
environment.

+# generate-ci
+
+This is the generator for GHC's GitLab CI infrastructure. In particular, this
+generates `.gitlab/jobs.yaml`, which is a YAML (or, strictly speaking, JSON)
+file which defines the bulk of the validation, nightly, and release jobs of
+GHC's CI.
+
+
+## Modifying the CI configuration (nix)
+
+The jobs are defined in `gen_ci.hs`. After modifying this you can run
+```sh
+nix run .gitlab/generate-ci#update-ci
+```
+from the top of the GHC repository to update the generated configuration.
+
+
+## Modifying the CI configuration (without nix)
+
+One can run `update-ci` without Nix as follows (assuming one has `jq`,
+`cabal-install`, and GHC installed):
+```sh
+$ cabal build generate-ci
+$ PATH="$(dirname $(cabal list-bin generate-ci)):$PATH"
+$ ./update-ci
+```
