Subject: [PATCH] fix(route): fixes "this route is empty" for copymanga (#8960)

* fix(route): fixes "this route is empty" for copymanga

This fix mirrors manhuagui logic updated in [1] - returns all items
when chapterCnt is 0 or not specified.

[1] https://github.com/DIYgod/RSSHub/pull/8670

* Add myself to `author` in docs/

This helps refactoring routes to v2. See
https://github.com/DIYgod/RSSHub/pull/8960#issuecomment-1030617999

* Add more authors

Ref: #8670
