This PR adds a setting to prevent projects from being shared in public
channels.
This can be enabled by adding the following to the project settings
(`.zed/settings.json`):
```json
{
"prevent_sharing_in_public_channels": true
}
```
This will then disable the "Share" button when not in a private channel:
