Polish Translation Final Steps

[Nat Alison]

Congrats on almost finishing the core of the Polish translation! There are a couple more tasks we need to do before we mark the core pages as complete.

• Change the DocSearch API key . One of the maintainers needs to sign up for DocSearch
• Go over the pages of the site one last time to check for consistency

The only real issue I found was that the header is kind of cut off -- you could fix this by decreasing the right margin on the "React" logo and/or decreasing the padding on the nav links.

Reopening in order not to forget about DocSearch API key.

I'm going to close this ticket as the core part is 💯%
