Test for malformed input URLs

[sergeychernyshev]

Currently we only test for http(s):// prefix on the URLs before accepting the input.

This can fail later in the process.

Test URL for well-formness before proceeding - probably update the check for the protocol to use that parsed URL instead of a regex.

That regex seems to be have been taken from the Zod docs.

There is not really that many rules on URLs, since DNS can handle unusual local network names as well as the general internet.
See #295 for some things I did.

I was planning to both use URL constructor to check for URL validity and checking the protocol property of said URL instead of regex.
