suggestion: don't suggest SNAP/SNAPSHOT versions unless I'm already on one

[SethTisue]

I'm seeing this with ScalaTest a lot lately

e,.g. if I'm on 3.1.0-SNAP1, then a PR upgrading to 3.1.0-SNAP2 is helpful

but if I'm on 3.0.x, a PR upgrading to 3.1.0-SNAP2 is likelier to be annoying than helpful

real-world example of annoyed maintainer: scala/scala-swing#106

scala-steward inherits this behavior from sbt-updates. If I'm correct it will only suggest 3.1.0-SNAP2 as update for 3.0.x if x contains a hyphen, for example if x = 8-RC2 as it is the case in the linked PR. It won't suggest that update if x consists of digits only.

I agree that it is not helpful to suggest PRs that go from RC to SNAPSHOT versions. It should be easy for scala-steward to filter any update where the new version contains SNAP but the current version don't.

Ok, I just merged #485 so these PRs should not happen anymore. And btw, thanks for the report Seth!

no problem, thanks for the prompt patch, that's awesome!
