Downstream in ghcup-ci we use the CONFIGURE_ARGS variable to determine
how to setup all the different jobs.

On the downstream trigger this was being inherited from the default
setting in .gitlab.yml file.

Therefore this led to job failures as the necessary CONFIGURE_ARGS were
not being passed to the configure script when installing the bindist.

See docs:

* https://docs.gitlab.com/ee/ci/yaml/#inherit
* https://docs.gitlab.com/ee/ci/yaml/#triggerforward

1. inherit:variables:fals
  - This stops the global variables being inherited into the job and
    hence forwarded onto the downstream job.

2. trigger:forward:*
  - yaml_variables: true (default) pass yaml variables to downstream,
    this is important to pass the upstream pipeline id to downstream.
  - pipeline_variables: false (default) but don't pass pipeline
    variables (normal environment variables).

Fixes #25294
