We need to write an adaptation module similar to existing modules - gallery or peom

Results of testing of <score> tag support

• Tested on these language pairs: en>iw, en>zh, en>gu, en>es, en>ji, fr>ru
• Tested both Lilypond and ABC notation.
• Tested both block and inline <score> elements.
• Tested all translation engines available for the language pair.

Could find only ONE instance in which a <score> element was not translated, and that was when testing en>zh and using the Youdao translation engine. I could successfully translate plain text with Youdao, but when I attempted a <score> element, I got the error message "machine translation failed," and the translation block was left empty.

In every other situation, translation of <score> worked perfectly. Even in the specific page and language pair mentioned above
(https://en.wikipedia.org/wiki/Also_sprach_Zarathustra_(Strauss) in en>iw), <score> elements translated without trouble, even
though the bulk of the normal text did not (because apparently the source article uses templates that aren't available in the
target language.)

Although support for musical notations, i.e. <score> when editing in ContentTranslation seems to be fine, and, the translation could be successfully done, some specific issues still present for translation of articles with <score> tags (thx to @KartikMistry to point it out). After re-testing, I decided to create a separate task since it seems that the problem with <score> tags differs from what is described in this task and is more general - T216859.
