chore: bump to 4.0.0

due api changes, it causing another part couldn't be used (Semver)

style: Standardize font to roboto

 the font family for the lyrics container (`#lyrics-plus-container`) has been changed from `YouTube Sans` to `Roboto`. Cuz YouTube Sans sucks.

Fix: Google Translate API response parsing

Adjust the extraction of translated text from the Google Translate API response. The translation segments are now correctly accessed from the first element of the response data array.

Improve Google Romanization accuracy

Refactor the Google Romanization function to first detect the source language from the full text context before romanizing individual segments. Previously, the API used 'auto' language detection for each small text part, which could lead to less accurate romanization results. By explicitly providing the detected language from the combined text, the romanization API receives more reliable language hints, enhancing overall accuracy. Also adds more robust error handling for API calls.

Merge a new refactor code to the main

Merge new scrolling system to the main codebase branch

bump: bump to 2.1.0
