Subject: [PATCH] connect: change verbose IPv6 address:port to [address]:port

- Use brackets for the IPv6 address shown in verbose message when the
  format is address:port so that it is less confusing.

Before: Trying 2606:4700:4700::1111:443...
After: Trying [2606:4700:4700::1111]:443...

Bug: https://curl.se/mail/archive-2022-02/0041.html
Reported-by: David Hu

Closes #9635
