@schemes annotation doesn't populate SwaggerInfo.Schemes in generated docs.go

[greddy2193]

Describe the bug
The @schemes annotation correctly generates the schemes array in swagger.json and swagger.yaml, but the generated docs.go file has an empty Schemes slice in SwaggerInfo. This causes the runtime template {{ marshal .Schemes }} to render an empty array when serving Swagger UI.

To Reproduce
Steps to reproduce the behavior:

1. Add // @schemes http https annotation in your main.go
2. Run swag init
3. Open generated docs/swagger.json - observe "schemes": ["http", "https"] is correct
4. Open generated docs/docs.go - observe Schemes: []string{} is empty

Expected behavior
The Generated docs.go should contain:
var SwaggerInfo = &swag.Spec{
Schemes: []string{"http", "https"},
// ...
}

Instead, it generates:
var SwaggerInfo = &swag.Spec{
Schemes: []string{},
// ...
}

docs.SwaggerInfo.Schemes = []string{"http", "https"}
}
