chore: Omit minified files and sourcesContent in published packages

[kitten]

Summary

We shouldn't publish with minified files due to the source map sizes and increased publish size. They're not meant to be used directly and we mostly relied on them for measurements.

Definitely a trade-off, but we shouldn't include sourcesContent. It likely doesn't help debugging much over our "half prettified" outputs and increases size substantially

Set of changes

• Disable sourcesContent when publishing
• Disable minified bundle output when publishing
