Remove CI_PROJECT_CONFIG_PATH variable
Why are we doing this work
CI_PROJECT_CONFIG_PATH was introduced as a pre-defined project variable in 13.8.
In 13.10, it was reported to be same as the existing variable
CI_PROJECT_CONFIG_PATH was therefore was set for deprecation in 13.10 with a notice that it will be removed in 14.0.
This issue is tracks the removal of
CI_PROJECT_CONFIG_PATH in 14.0
- Remove variable from list of project variables
- Update corresponding specs
- Remove reference from docs
