Pull request overview

This pull request updates the OneOf documentation and removes unnecessary EnableOneOf configuration code throughout the codebase. The changes reflect that OneOf is no longer an experimental feature and is now enabled by default in HotChocolate v16. The documentation has been corrected to use the proper introspection field name isOneOf instead of the incorrect oneField.

Changes:

• Corrected OneOf documentation to reflect that it's now a standard feature (enabled by default) rather than experimental
• Fixed introspection field name from __Type.oneField to __Type.isOneOf in v16 documentation
• Removed unnecessary ModifyOptions(o => o.EnableOneOf = true) calls from tests and code generation utilities
