Feature Request: Add supabase_storage_bucket resource

[bhusareMayur]

Description

Currently, the Terraform provider lacks a way to manage Supabase Storage buckets. Storage is a core capability, and allowing users to provision and manage buckets via Terraform would be highly valuable for infrastructure-as-code workflows.

I would like to propose and build the supabase_storage_bucket resource.

Proposed Solution

Implement full CRUD operations for storage buckets utilizing the Supabase Storage API.

The initial schema would likely include:

• id (String, Computed)
• project_ref (String, Required)
• name (String, Required)
• public (Bool, Optional, Default: false)
• file_size_limit (Int, Optional)
• allowed_mime_types (List of Strings, Optional)

Additional Context

I recently contributed the endpoint validation and whitespace trimming feature (supabase/terraform-provider-supabase#352) and would love to tackle this next. Please let me know if this schema looks good and if you would accept a PR for it. I am ready to start building!
