Tekstowo lyrics source needs to be adapted to new website layout

[wisp3rwind]

From #4228

That's probably the same thing that makes our weekly integration tests fail, cf. e.g. https://github.com/beetbox/beets/actions/runs/2046155673

The Tekstowo source needs to be fixed; I guess they updated their website structure at some point and our scraper now picks up extraneous text?

Googling this issue brought me here. I think this was fixed in 3f896ab? I use Tekstowo a lot.

See #4344: Probably there's no issue, but a report based on an old version of beets. Feel free to re-open or create a new issue if this is not true.
