Addiction API endpoints for project environments.

[char-ptr]

Currently there exists endpoints for getting project environments but no such endpoints exist for creating, or deleting.

Here in the source shows there exists only getting the environments associated with the project
https://github.com/coollabsio/coolify/blob/main/app/Http/Controllers/Api/ProjectController.php#L103-L159

I think it would be beneficial to include such endpoints for further extensibility.
