fixed minor TS typing issues in class Result and output.result

[danielrentz]

Motivation/Description of the PR

Two small fixes for Typescript typings:

• the function output.result misses a declaration for the optional parameter "failedHooks".
• the "failures" in class Result may contain numbers or strings. The exact type for a single failure report is [string, number, string, string, string] but that is not possible to declare with vanilla JSDoc. Added typedef Failure as string/number array, and replaced string[] with the new type.

Unrelated changes in plugins.md have been auto-generated by npm run docs.
