Switch version numbers to 4.0, enable builds

I think 123 is the right build number to start on. 3.3.0 (former main) builds are going to be 286, but this continuity isn't a problem.

• Removing the manifest/4.0.xml entry may skip building that manifest unless it's included elsewhere. Verify that its removal won’t prevent the 4.0 pipeline from executing.

• [nitpick] The release version in manifest is 4.0.0 but the OpenAPI specs use 4.0. For consistency and clarity, consider using the full semantic version 4.0.0 here.
