Fixed a small typo on the program name

This was found when printing out the version of the program.

Sadly this isn't a typo, as @vrothberg said this is a silly workaround for Docker hard-coding how they detect tini's version. If you change it, Docker starts giving scary (and completely pointless) warnings.

Ah right, it wouldn't be a bad idea to add a comment.

Added a comment with a text based on @vrothberg's explanation (thanks!).

LGTM.
