build: fix deploying of screenshot functions

* Updates the dashboard and screenshot deploy script to exit the process immediately if the Firebase token is not set.
* Fixes that the error message of the dashboard still shows the old name of the token variable
* Renames the screenshot variables to follow the dashboard environment variables
* Explicitly specifies the project that will be uploaded in the screenshot deploy script (same as for dashboard)
