Issue Description

At the moment when the library parser tries to parse a devfile with schemaVersion=2.2.2 or schemaVersion=2.2.1 we get the error:

Error: failed to generate index struct: /build/stacks/dotnet60 devfile is not valid:
failed to populateAndParseDevfile: unable to find schema for version "2.2.2".
The parser supports devfile schema for version 2.0.0, 2.1.0, 2.2.0, v1alpha2

As seen in the pkg/devfile/parser/data/versions.go there is no reference for the 2.2.1 or the 2.2.2 versions.

Acceptance Criteria

• Devfile library supports Devfile schema versions 2.2.1 & 2.2.2

Steps to follow:

1. Update the pkg/devfile/parser/data/versions.go to include 2.2.1 & 2.2.2
2. Cut a pre-release for 2.2.3-alpha in the devfile/api.

Created PR to add support for 2.2.1 and 2.2.2 here: devfile/library#208

When we cut the pre-release for 2.2.3-alpha it is probably best to open another PR to library to have a 2.2.3 alpha version recognized. I noticed 2.2.1-alpha was being used prior. wdyt?
