JsonSerializerContext source generation fails with keyword identifiers #64159
Description
Description
When a type containing a keyword identifier (e.g., @base) is used with JsonSerializerContext's source generation, compilation fails with several errors:
1>System.Text.Json.SourceGeneration\System.Text.Json.SourceGeneration.JsonSourceGenerator\CK3JsonContext.Weight.g.cs(55,78,55,82): error CS1001: Identifier expected
1>System.Text.Json.SourceGeneration\System.Text.Json.SourceGeneration.JsonSourceGenerator\CK3JsonContext.Weight.g.cs(55,78,55,82): error CS1003: Syntax error, ',' expected

Reproduction Steps
Define a type that includes a keyword identifier:
public class Weight
{
public int @base { get; set; }
public int current { get; set; }
public int target { get; set; }
}and add it to a JsonSerializerContext:
[JsonSerializable(typeof(Weight))]
internal partial class CK3JsonContext : JsonSerializerContext
{
}Expected behavior
Either source generation succeeds, or an error that keyword identifiers are not supported is emitted
Actual behavior
Generated source gets mangled and breaks compilation in an opaque way
