fix(build): Ensure tree shaking works properly for ESM output (getsentry#11122)

Apparently, webpack looks at `sideEffects` in the generated
package.json, and based on this does not tree shake correctly 😬

I also bumped webpack (one of the things I tried while debugging
this...).

This now puts the original `sideEffects` value from the original
`package.json` and puts it into the esm package.json.
