Contributors to FreeBSD: make the article more relevant and appealing

[grahamperrin]

Summary

Affects:

• Contributors to FreeBSD | FreeBSD Documentation Portal.

Don't begin the article with the one and only section that is (much) more than twelve years out of date.

Move the Donors gallery to the end. Improve it a little – not forgetting a link out to The FreeBSD Foundation.

Other than that nit (fixable on commit), LGTM.

While here, maybe remove the spurious space starting the link text?

Whilst removing the white space, I dealt with a few other nits in the (still outdated) gallery.
