typescript 5.4.2 generates invalid types for `test`

[mdonnalley]

Describe the bug Latest @oclif/test uses typescript 5.4.2, which causes consumers to run into compilation errors:

node_modules/@oclif/test/lib/index.d.ts:3:28 - error TS2315: Type 'Fancy' is not generic.

  3 export declare const test: import("fancy-test").Fancy<import("fancy-test/lib/types").Context, {
                               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  4     skip: {
    ~~~~~~~~~~~
...
111     };
    ~~~~~~
112 }>;
    ~~

To Reproduce Install latest @oclif/test into @oclif/plugin-version and run yarn test

Expected behavior No compilation errors
