annotations.md: Fix missing URLs to some guides

[bugwelle]

It seems some URLs were missing. See screenshot below.
Also note that the annotation @Common.FieldControl is not mentioned anywhere else. Is something missing here?

Thanks. In the old repo, these links were probably in the central links.md file that was included everywhere. We no longer support this here.

@chgeo I think it would be worth to grep for see [ in the rendered HTML. There are a few other places where a link is still missing. :-)

[chgeo]

Good point. Will do.

Fixed
