Fix: wrong Lilypond Lyrics plugin description

[Gootector]

In Home -> Plugins -> Lilypond Lyrics, MuseScore Studio shows wrong description: 'sTr("Apply lyrics in lilypond format."'
'qsTr()' is unnecessary here. The plugin descriptions are also without dot at the end.

Mmm... in this file:

I believe it is actually a bug that the description field of plugins is not translatable

'qsTr()' is unnecessary here.

Really? Right now, it doesn't do anything because the strings from plugins are not pushed to Transifex, but this is something we want to do in the future.

[Jojo-Schmitz]

That's why I claim it to be a bug (in the Plugin API, not this particular plugin). it should just show the untranslated string (here: Apply lyrics in lilypond format.) rather than the (partial!) description property (here: sTr("Apply lyrics in lilypond format.")

This bug doesn't occur in 4.3.0, in Qt 5. So - should I close my PR?

[Jojo-Schmitz]

Yes, I guees so. We'd need an issue opend on the non-translatability of the plugin description though
