Name our release profile sonatype-oss-release instead of release.

This matches what we do for most of our other projects.

(Compile-Testing seems to be the only project that uses a particular feature, `<releaseProfiles>`, so I'm kind of just guessing that I need to update the value there to match.)

Motivation: I had trouble releasing 0.20 in part because I was trying to use `-P sonatype-oss-release`. I eventually succeeded by setting _both_ that _and_ `-P release`, but it would be nice not to need that next time. The specific problem appeared to be at least partially about getting an ancient "default" version of `maven-gpg-plugin` instead of the version specified inside the release profile. (And then I had an additional issue from possibly losing my `.m2/settings.xml` when I got a new machine....) Hopefully this new fix is correct, though I guess I'll have to carefully start but not finish a release to be sure.
