[AlokSwaminathan]

Checklist:

• [ x] Updated source's version for individual source changes
• [ x] Updated all sources' versions for template changes
• [ x] Set appropriate nsfw value
• [ x] Did not change id even if a source's name or language were changed
• [ x] Tested the modifications by running it on the simulator or a test device

The method for finding and ordering the pages works by reading the pages object in the hydration JSON data, but I don't know how reliable that is. The fix works on the manhwa I have tested, but it could break.
