What version are you seeing the problem on?

1.18.2

Describe the issue

I tried burning music from 'music.163.com' in the etching table.
The result is "Unsupported Content-Type: audio/mpeg; charset=UTF8" error.

latest.log

none

I used this link: http://music.163.com/song/media/outer/url?id=1874120860.mp3

But this link can be played normally on the radio

Did a quick search, the bug is caused by this line:
https://github.com/MoonflowerTeam/etched/blob/d4771029027b87bfaf8ee522009aaf8a8211f29e/common/src/main/java/gg/moonflower/etched/common/menu/EtchingMenu.java#L179

Apparently http content types can have derivatives, thus need to be split when matching to the string table VALID_FORMATS.

I will try to do a local build and see if this fix works.
