refactor: update title formatting

[Keith94]

Makes it match osc.lua defaults.

Any opinions on defaulting to ${media-title/no-ext}? Assuming the file in question has a title set, there shouldn't be a difference, but in the event there isn't one and it falls back to the file name, omitting .mkv or .flac could keep things less cluttered. More so asking to see what everyones opinion is on it, not for any immediate changes.

We used it before but it was removed due to a bug: #30

Sam provided a workaround for that though.

Awesome! Thank you very much, I didn't even realize those notes weren't updated.

Changes to your PR:

• fix: value for screenshot_flag. should be subtitles, not subs
• fix: correctly close table row with | for the language option row
• refactor: default title to ${media-title}. mpv relies on playlist positions because the stock OSC doesn't include native playlist button or tooltips. In ModernZ title would look cluttered with [2/5] title. Nevertheless, the user has the option to modify it to their liking.

Thanks for the fix 😃
