[morphar]

This commit should be tagged as v0.6.3

[morphar]

@timburks as far as I understand, this pull request and #289 should fix the multi-module issues.

1. merge Retract breaking multi-module commit #288
2. create tags:
   cmd/report-messages/v0.6.3
   cmd/vocabulary-operations/v0.6.3
   cmd/report/v0.6.3
   cmd/protoc-gen-openapi/v0.6.3
   cmd/protoc-gen-jsonschema/v0.6.3
   cmd/petstore-builder/v0.6.3
   cmd/parse-linter-output/v0.6.3
   cmd/disco/v0.6.3
3. merge Remove multi module #289
4. tag v0.6.4

If this fixes the issues, it should probably have a release as well, right?

@morphar Thank you!

@morphar I am unable to create the cmd/ tags with the leading slash. Looking at your comment here, I think the leading slashes may have been added to your note above unintentionally. I'll proceed and create tags without the leading slash.

@timburks You're absolutely right, the leading slash is wrong.
I have removed them from the comment, just to avoid confusion for anybody else reading it :)

@morphar Thanks! The tags are pushed now, so I'll proceed with the next merge and tag.
