Auto Bump default version doesn't work for non-interactive release

[alexserdukov]

I am trying to apply plugin to my build.
The setup is pretty basic:

version.sbt:
ThisBuild / version := "0.1.0-SNAPSHOT"

plugins.sbt:
addSbtPlugin("com.github.sbt" % "sbt-release" % "1.4.0")

First release went fine:
Release version was set to 0.1.0 from 0.1.0-SNAPSHOT
Next version was set to 0.1.1-SNAPSHOT

But on subsequent release it set the version to 0.1.0 instead of 0.1.1

Documentation says the following:
Release Version: current version without the qualifier (eg. 1.2-SNAPSHOT -> 1.2)

Why the version was changed from 0.1.1-SNAPSHOT to 0.1.0?
