[Bug]: Shared variables not inserted properly in a compose project #8918

Error Message and Logs

For example: if I were to use {{environment.DRAGONFLY_URL}} for a service, it'd show the full Redis URL in the environment view, but inside of the container it is a literal. Which means that I get something like: URI::InvalidURIError: bad URI (is not URI?): "{{environment.DRAGONFLY_URL}}" (URI::InvalidURIError).

Steps to Reproduce

1. Define a shared variable for the environment.
2. Use the variable in a service.
