content: rename articles to reinforce convention of short URLs

The Go blog started out on Blogger (http://web.archive.org/web/20100325005843/http://blog.golang.org/). Later, we moved to the current self-hosted blog server with extra Go-specific functionality like playground snippets. The old Blogger posts have very long URLs that Blogger chose for us, such as "go-programming-language-turns-two" or "two-go-talks-lexical-scanning-in-go-and", predating the convention of giving posts shorter, more share-friendly, typeable names. The conversion of the old Blogger posts also predated the convention of putting supporting files in a subdirectory. The result is that although we've established new conventions, you wouldn't know by listing the directory - the old Blogger content presents a conflicting picture. This commit renames the posts with very long names to have shorter, more share-friendly names, and it moves all supporting files to subdirectories. It also adds a README documenting the conventions. For example, blog.golang.org/go-programming-language-turns-two is now blog.golang.org/2years, matching our more recent birthday post URLs, and its supporting files are moved to the new 2years/ directory. The old URLs redirect to the new ones.

+See https://pkg.go.dev/golang.org/x/tools/present?tab=doc
+for documentation of the file format or look at any of the

+
+Article file names should be short, amenable to being typed by hand in URLs.
+Typically article file names are up to three words, separated by dashes.
+A trailing year in the name typically does not have a dash before it.
+
+All supporting files for an article, even if there's only one, should be
+placed in a directory named for the article (minus the .article suffix).
+
+If your article has code that is meant to be a working program, please use
+.code, or ideally .play, to load the lines from a supporting .go file.
+That way you can easily check that the .go file, and therefore the code
+in your article, still works.
+
+Please use .image and .video to embed images and videos,
+instead of using raw HTML tags. The .image and .video commands
+provide a way to adjust the implementation of those embeddings
+all in one place.
+
+Please use .html when it is necessary to add large blocks of HTML,
+keeping article text in the main .article file. Another important use of
+.html is to factor out an HTML snippet that appears multiple times.
+Short HTML sequences, like <div><center> or </div></center>,
+are fine to put directly in the article files.
