UI feature to export/import project.yaml file

If a user wants to reuse the project configuration or “template” another user created, then they need to use the CLI openfn deploy commands to import a project.yaml file. This is a very technical process, and it would be way easier if they could just click a button to export/import a project.yaml file. This would encourage workflow sharing among the community - and could help us to build a library of workflow examples.

(Also, I’m not 100% sure if users of the OpenFn SaaS on app.openfn.org can do this project.yaml import step if they’re not super admin users? We had issues with this historically, so not sure if it’s been resolved.)
