feat: change default value of processDynamicNodeImports

[eduardoboucas]

- Summary

The processDynamicNodeImports configuration property controls whether esbuild should add a runtime shim to any imports using dynamic expressions. The feature flag in Netlify Build that controls this value has been fully rolled out to production, so we can begin its removal.

This PR changes the default value of processDynamicNodeImports to true, but still allows the functionality to be switched off if the value of the property is false.

- Test plan

Tests updated.
