Translate "How to interpret phylogenetic trees" into Polish

We’d like to translate “How to interpret phylogenetic trees” into Polish. This narrative is referenced in the latest hCov-19 report, and we hope it will help make that one and future situation reports more accessible. The file to translate is ncov_trees-background_pl.md in branch background_pl under the narratives folder: https://github.com/nextstrain/ncov/blob/background_pl/narratives/ncov_trees-background_pl.md

After pushing your changes to GitHub, you can preview the translation here: https://nextstrain.org/community/narratives/nextstrain/ncov@background_pl/trees-background/pl/

Please add your name under translators and your professional link under translatorLinks, so we can credit your work.

If more than one of you are working on the document at a time feel free to use a live, online editor like hackmd (sign in with GitHub) to work. The French translation group has found this especially helpful, whatever works best for you.

As always, THANK YOU! It’s an honor to work with you both.

Hi @aniafijarczyk, I have read the whole text and added some minor changes - found some typos or put/delete commas mainly. I hope it is fine! I didn’t notice anything else to correct.
