Initial letter of word Prijs should be upper-case

[marlenereithmayr]

Hey.

There are multiple occurrences in the nl_NL file where the initial letter of the word Prijs is lower-case instead of upper-case. In the github_contributions.csv it is already correct. Please update the nl_NL file too.
Eg: "Price","prijs","module","Magento_Sales"

Thanks in advance.
