Well...that's a weird mistake from my side. Nice catch and thanks for the PR!

Merging it now, but out of curiosity, was it difficult to change? I purposefully used .svg so that others could update them if necessary. What tooling did you use for that?

I first tried to change it using inkscape, but the diff showed more changed lines than I wanted so I just changed the single word in a text editor.
