The enum_name argument for enum_variant_name fn of ParseCallbacks trait includes the enum keyword along with the name

If I run the following code with bindgen version 0.71.1 (latest as of this moment):

fn main() {
    let code = r"
        typedef enum MyEnum {
            MyEnumVariantA,
            MyEnumVariantB,
        } MyEnum;
    ";
    #[derive(Debug)]
    struct ParseCb;
    impl bindgen::callbacks::ParseCallbacks for ParseCb {
        fn enum_variant_name(
            &self,
            enum_name: Option<&str>,
            _original_variant_name: &str,
            _variant_value: bindgen::callbacks::EnumVariantValue,
        ) -> Option<String> {
            dbg!(enum_name);
            None
        }
    }
    bindgen::builder()
        .parse_callbacks(Box::new(ParseCb))
        .header_contents("temp.h", code)
        .generate()
        .unwrap();
}

I get this output:

[src/main.rs:17:13] enum_name = Some(
    "enum MyEnum",
)
[src/main.rs:17:13] enum_name = Some(
    "enum MyEnum",
)

We should only get the MyEnum part. If this is not a bug, then, it should at least be documented in the function docs.

Temporary workaround: just do enum_name.strip_prefix("enum ") (note the space after the enum keyword).

Start at the ParseCallbacks::enum_variant_name entry point and reproduce the issue with the provided header_contents example. Trace how the enum name is passed to the callback, then verify that the callback receives only MyEnum or that the function documentation clearly describes the existing value.
