[pt/animesgratis(Top anime)] Fix Selectors

[Bashousen]

With the previous selector, it's not possible to find episodes of some anime series. For example: https://topanimes.net/animes/hora-de-aventura-4/. This new selector solves that problem.

Checklist:

• Updated extVersionCode value in build.gradle for individual extensions
• Updated overrideVersionCode or baseVersionCode as needed for all multisrc extensions
• Referenced all related issues in the PR body (e.g. "Closes #xyz")
• Added the isNsfw = true flag in build.gradle when appropriate
• Have not changed source names
• Have explicitly kept the id if a source's name or language were changed
• Have tested the modifications by compiling and running the extension through Android Studio
• Have removed web_hi_res_512.png when adding a new extension
• Have made sure all the icons are in png format
