Issue on docs

Path: /configuration/environment-variables

Might be a good idea to include built-in ENV VARs that Qovery inject for version control systems; I was looking for the git commit SHA, and found through AI in the docs, but it's never mentioned.

It says it's QOVERY_COMMIT_ID; Here's the AI assistant response:

The built-in variables list doesn't include a git commit SHA. Let me check the pipeline build phase and Dockerfile docs for build args.The documentation doesn't list a built-in environment variable exposing the git commit SHA during build. Let me do one more targeted check.Found it. The Datadog integration page shows $QOVERY_COMMIT_ID. Let me confirm.Qovery injects a built-in variable QOVERY_COMMIT_ID containing the git commit SHA. You can reference it in your service's environment variables (e.g., DD_VERSION=$QOVERY_COMMIT_ID) or pass it as a Docker build ARG in your Dockerfile to expose it during the build phase. Note that ARGS variables also influence build caching (see image-mirroring docs).

(Build Phase / Pipeline)[/configuration/deployment/pipeline]
(Image Mirroring)[/configuration/deployment/image-mirroring]

Open the documentation page at /configuration/environment-variables and review how built-in environment variables are listed. Document QOVERY_COMMIT_ID as the git commit SHA variable, including the use case described in the issue, then verify the surrounding links to the pipeline and image-mirroring pages remain appropriate.
