All OpenAPI customization documentation broken in .NET 10 previews

[DillonN]

Description

The customization documentation is broken in .NET 10 previews as apparently the types returned have changed.

E.g. this example from the docs:

builder.Services.AddOpenApi(options => {
    // Schema transformer to set the format of decimal to 'decimal'
    options.AddSchemaTransformer((schema, context, cancellationToken) =>
    {
        if (context.JsonTypeInfo.Type == typeof(decimal))
        {
            schema.Format = "decimal";
        }
        return Task.CompletedTask;
    });
});

Causes compile error:

CS0200: Property or indexer 'IOpenApiSchema.Format' cannot be assigned to -- it is read only

This is making my applications incompatible with .NET 10. What is the recommended way to make format transformations now?

NVM, was looking at a level nested below with Properties. Top level still has a setter.
