Docs: convert reference links to standard links

What does this MR do?

This MR corrects the reference-style links in the following pages, with one exception:

	modified:   development/changelog.md
	modified:   development/code_review.md
	modified:   development/contributing/issue_workflow.md
	modified:   development/documentation/styleguide.md
	modified:   development/ee_features.md
	modified:   development/file_storage.md
	modified:   development/interacting_components.md
	modified:   development/performance.md

development/code_review.md contains some footnotes, which are styled like reference links, and I'm not sure how we want to style those. (@marcel.amirault, FYI.)
