Feature req: Add more info avout target env to Transforming errors

[capaj]

Currently I am using Vite 2.0.5 which uses esbuid 0.8.57

npx vite build
vite v2.0.5 building for production...
✓ 698 modules transformed.
error during build:
Error: Transform failed with 1 error:
assets/vendor.51812f80.js:12726:8: error: Transforming for-await loops to the configured target environment is not supported yet

Would be nice if it printed out the target environment too. This is handled by Vite so I have no idea what it actually is configured to.
