src/goEnvironmentStatus.ts: handle failed getGoVersion call

getGoVersion can return undefined. Handle the case and display
 `Go (unknown)` in the status item.

Made formatGoVersion to take GoVersion or undefined.

Also, utilize GoVersion.format(includePrerelease) to choose
the correct version string. It turned out GoVersion.format
uses sesmver.format, which reformats version strings like 1.14rc1
to 1.14.0. That's not ideal for go version display purpose.
