docs: fix typos in two files

[StargazerCel]

I need to add this hashtag at the end because I am contributing in a project at my university.

Can you put the hashtag in the comment rather than the title? It's very distracting where it is and irrelevant to everyone in the world, aside from one.

[StargazerCel]

Sorry for the inconvenience but the hashtag has to be in the title. We are bound to certain instructions for it to count into our project.

Give them links to these PRs and I can explain to them how we do not accept rubbish here because of silly external processes. Sorry. We have a project to run here.

Thanks!
