[decentralized] Consider replacing word "recommendations" in the intro

[lbdvt]

The introduction statement of the Decentralized Web Interest Group charter is:
"The mission of the Decentralized Web Interest Group is to evolve recommendations to further the W3C’s One Web purpose by identifying, balancing and mitigating the unintended impacts of proposals early in the process, encouraging uniform change, and promoting OpenStand principles."

"Recommendations" are, in W3C terminology, standards that have been published through a specific process and through a Working Group.

To avoid confusion, "recommendations" should be replaced by another word, e.g.: "guidelines".
