zeta: Fix data collection display on the status bar menu (#24177)

Follow-up to: https://github.com/zed-industries/zed/pull/24031

This PR adds a new function that allows the UI also to display the state
of the data collection. Previously, we only showed that if the project
adhered to the `is_open_source` condition. Now, we show it for all
projects.
