Remove disruptive regex for URL validation

[Fra146]

The provided changes remove a very destructive regex.

I will provide the lighthouse reports for the before and after

It would seem that this causes a recursion when checking for the validity of social media links. I'm unsure of when this happens exactly (on a blank site nothing happens) but on my full site it does slow the page down by 14 seconds.

After more analysis it would seem that this regex is executed for each entry of the social media in the site footer
var followSocialMedia = {
instagram: ["https://www.instagram.com/verylongexamplestring?ref=example.it", "Example Site"],
}
That kind of instagram links makes the regex spiral into a very long recursion. (It's specifically the long link followed by the ?ref)
