Dušan Vlahović's name being listed incorrectly / Scraper incorrectly handling š symbols

[tvqt]

Hi there,

I was going through the data earlier, and I noticed Dušan Vlahović was being listed as "Du Scaron An Vlahović". On further investigation, that is how his name is written in his Transfermarkt URL, and the š symbol is known as a caron

FYI @tvqt

With this PR we should ve ready to solve this problem in the dataset repo. I'm moving the issue there.
