Steps to reproduce the issue

If you use com_banners with external advertisers, sometimes you have the work with very long urls.
When you have a long base url + utm_source + utm_medium + utm_campaig + utm_content etc it easily hits the varchar(200) limit in #__banners.clickurl

Expected result

Allow longer clickurl

Actual result

On save you'll get an error: Data too long for column 'clickurl' at row 1

System information (as much as possible)

Joomla 4.2.8
PHP 8.1

Additional comments

In my current case I have an url with 250 characters, I'm not sure what would be the best length for the varchar, but more than this.
Using external url shortener services are not acceptable, because the advertiser's policy doesn't allow using it. Maybe because the referer parameters or the stats, I'm not sure.
