Subject: fix(ext/console): Error Cause Not Inspect-Formatted when printed
 (#24526)

This pull request addresses an issue where the Error.cause property was
not formatted correctly when printed using console.log, leading to
confusion.

solution:
Implemented a fix to ensure that Error.cause is formatted properly when
printed by console.log, and the fix done by using JSON.stringify

This PR fixes https://github.com/denoland/deno/issues/23416
