Swift / XCode Builds Fail

# Improve documentation ## Link [Add a link to the page which needs improvement (if relevant)](https://supabase.com/docs/reference/swift/installing) ## Describe the problem XCode will fail to build with the error "No such module 'Supabase'" until the user adds Supabase explicitly to the targets. See [this github issue](https://github.com/orgs/supabase/discussions/19764). Flow: 1. Install supabase 2. Frameworks look like this (no Supabase) <img width="830" height="215" alt="Image" src="https://github.com/user-attachments/assets/be0d37c9-0fcb-4e0e-bc98-a679bf49357f" /> 4. Build fails 5. Add supabase explicitly <img width="557" height="552" alt="Image" src="https://github.com/user-attachments/assets/4b7d1b2f-bf49-4503-9b37-3bd1cb05660c" /> <img width="773" height="250" alt="Image" src="https://github.com/user-attachments/assets/ce8d61f0-c858-4707-bc87-448c6d9d0fe2" /> 6. Build succeeds ## Describe the improvement Either explain how to add it manually with my notes above, or fix the supabase swift package build to add it by default. ## Additional context Supabase is great <3
