Production may return error name in error information if current network error

[HuberTRoy]

Web3 Version is 6.1.9

Background:

When user in an unsupported network, I will give an error to user to switch.

All will work good in development but in production I cannot get the error name.

Now:

Use core.cjs.production.min.js:

Use core.cjs.development.js or core.esm.js:
