bug: `ts(optional_fields)` does not compile with generic parameters

[goldrushx21]

Describe the bug

error[E0277]: the trait bound `<T as TS>::OptionInnerType: TS` is not satisfied
  --> src/mypackage/src/lib.rs:1:10
   |
11 | #[derive(ts_rs::TS)]
   |          ^^^^^^^^^ the trait `TS` is not implemented for `<T as TS>::OptionInnerType`
   |
   = note: this error originates in the derive macro `ts_rs::TS` (in Nightly builds, run with -Z macro-backtrace for more info)

To Reproduce

#[derive(ts_rs::TS)]
#[ts(optional_fields)]
pub enum MyEnum<T> {
    MyVariant { my_field: T },
}

Expected behavior
No compiler errors

Screenshots

Version
v12.0.0

Additional context

Thanks for opening the issue.
The bug seems to be related to the interaction of #[ts(optional_fields)] with generic structs.

As a temporary workaround, you can add this attribute: #[ts(bound = "T: ts_rs::TS, <T as ts_rs::TS>::OptionInnerType: ts_rs::TS")]

While I don't think this is a regression, the error did change compared to v11.
