Broken link for validation

on the validation result page is a link suggestion how to link to the 
validation.

But it's mis-escaped and yields a 404 (in firefox v104).

Example:

after doing 
https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Frec.mro.name%2Fpodcasts%2Fradiowelt.rss

the result page falsely says:

-- snip -- snip -- snip -- snip -- snip -- snip -- snip -- snip --

If you would like to create a text link instead, here is the URL you can 
use:

     http://validator.w3.org/check.cgi?url=http%3A//rec.mro.name/podcasts/radiowelt.rss

-- snip -- snip -- snip -- snip -- snip -- snip -- snip -- snip --

Who cares about the check.cgi?

Cheers,
Marcus
