doc: Fix the typo in example output in url.md for url.hostname

[darkrishabh]

Currently in the url.hostname, the replacement example updates the hostname to use example.com:82 but in the comment it's showing the expected output for the operation to be // Prints https://example.com:81/foo

It should be // Prints https://example.com:82/foo

Checklist

• documentation is changed or added

Notice that you must first run console.log(myURL.href); prior to viewing the expected output.

Disagree w/ the changes, but I think this example could be more clear.

@DerekNonGeneric - thanks, and you are right. the hostname field is different than the host in that it does not include the port number, and hence changing that does not affect the rest of the url attributes.

@darkrishabh - this change is not correct. At the same time, I guess the doc can be improved to make it more explicit, to avoid confusion. Let me know if you can come up with a sentence.

the PR requires additional changes

Sorry for picking this up so late, I got involved in some family emergency. I agree with @jasnell and incorporated the change suggested.
