Remove needless cd from gitlab-ci.

[rcorre]

It seems that the workdir for gitlab is already inside the cloned repo, so cd $EXPORT_NAME will fail.

Here's a build that prints pwd to demonstrate: https://gitlab.com/rcorre/weekly-game-jam-204/-/jobs/1318895344

Here's a pipeline that passed after removing cd:

• https://gitlab.com/rcorre/weekly-game-jam-204/-/pipelines/315008027
• https://gitlab.com/rcorre/weekly-game-jam-204/-/commit/1af90b1fa2b9b74abb3e50a022809d700350bc10.

The cd is there because this repo includes an example project in another folder to organize between examples and godot-ci specific files, removing that will cause all my pipelines to fail. I know that godot projects are not usually included in a folder but doing this here would be confusing. Since the gitlab-ci.yml is a template for people to modify according to their needs I suggest you keep the cd command there and add a comment instructing people to remove it if their project root is not included in a folder

Thanks!
