Missing export for 'is' (type checking utils) in 1.20.2

What happened?

When trying to build a quasar app that uses an import for 'is' from the type checking utils, get a build error stating that "Unknown import from Quasar: is".

I was able to workaround by manually modifying the node_modules/quasar/dist/babel-tranforms/imports.js file. I added "is": "src/utils/is.js" to themap` object specified in the file.

What did you expect to happen?

Expected build to complete without the above error!
