Invalid typealiases generated for @actions/tool-cache

If you generate for @actions/tool-cache, the tool-cache.module_@actions_tool-cache.kt file contains these three:

typealias HTTPError = Error
typealias IToolRelease = IToolRelease
typealias IToolReleaseFile = IToolReleaseFile

For the first, #398 applies. But for the other two it seems little helpful to re-alias them. The according TS declarations are

import * as mm from './manifest';
export declare class HTTPError extends Error {
    readonly httpStatusCode: number | undefined;
    constructor(httpStatusCode: number | undefined);
}
export declare type IToolRelease = mm.IToolRelease;
export declare type IToolReleaseFile = mm.IToolReleaseFile;

And here the compilation errors:
