Add translation to saving content and cursor position sections

Mariana and I were trying to fork this repository using her account, but GitLab would continuously report that an error (Thor knows which) had occurred.

Thus, I proposed her to upload her contributions to my fork, from which I am creating this MR. Thus, both our sections, that is "Showing The Cursor Position" and "Saving The Content To A File", have been translated herein. They should be already merged just right. Be check it out, pls.

One more point. Before the Hackathon, check it out if the quotation marks symbols are correct in the source code excerpts. Visually, some of them seem not to be the regular characters. This might lead us to some problems with copying-and-pasting from the blog.

Thanks!
