Punctuation can make links non-functional in footprint description

Description

KiCad generates broken links from URLs in the footprint description/documentation if the URL is followed by a punctuation mark (e.g. comma). There are many footprints with this issue.

While commas can technically be part of a URL, they are unusual and it is even more unlikely that a URL ends with one. For this reason, I think it may be better to ignore punctuation marks at the end of URLs during link generation than correcting footprints individually and trying to rein in what may feel like a natural way of writing the description for contributors. Other software also ignore those punctuation marks when generating links from URLs in free-form text (e.g. Gitlab's own online IDE).

One example:

The clickable link points to: http://www.4uconnector.com/online/object/4udrawing/19963.pdf,

While the actual working URL is: http://www.4uconnector.com/online/object/4udrawing/19963.pdf

Steps to reproduce

1. Open the PCB editor
2. Go to Place --> Add Footprint
3. Fin footprint TerminalBlock_4Ucon_1x02_p3.50mm_Horizontal
4. In the description and documentation section, notice that the clickable link that ends with a comma is not functional
5. Notice that the link works if you remove the comma
