runtime(doc): remove outdated Contribution section in pi_tutor

runtime(doc): remove outdated Contribution section in pi_tutor

Problem: The Github repo link in the Contribution section has been
archived for 5 years. So people who want to contribute to the
tutor plugin should just send PR to Vim repo, similar to most
other Vim features, so there is no need for a Contribution
section in the plugin doc.

Solution: Replace it with an Original Author note at the beginning of
the help document.

It is recommended to use a less formal style when writing tutorials than in
regular documentation (unless the content requires it).
