fix(workspace): Fix sourcemap generation for “longer” bundles

[kitten]

Resolves #3182

Summary

It seems that during one of the past dependency upgrades sourcemap generation has slightly and subtly broken. For longer output bundles, the offset of sourcemaps would eventually be incorrect.

This was due to sourcemaps becoming broken in the cleanupPlugin, but since Rollup now provides an option for hoisted transitive imports, its use for JS output is now obsolete.

I've also noticed that we're losing a bit of sourcemap fidelity with Sucrase, and since we're already parsing all files with Babel, we can safely move to a Babel TypeScript transformer.

Set of changes

• Upgrade Rollup dependencies
• Replace sucrase with Babel transform
• Remove Babel import transform from cleanup plugin
• Disable hoistTransitiveImports in Rollup output options
