Improve web viewer by removing scrollbar on each RFC pages (overflow)

[jmaselbas]

Description

Reading RFCs with the html viewer at https://datatracker.ietf.org/doc/html/rfc2119 is not very comfortable because of spurious scrollbars for each individual pages, this brakes scrolling.

This can be "easily" fixed by removing the overflow:auto css property of pre elements:

 pre {
   margin-top: 0;
   margin-bottom: 1rem;
   font-size: .875em;
   display: block;
-  overflow: auto;
 }

which is defined in "_reboot.css" which I believe comes from bootstrap/scss/reboot
which is included by document_html.scss which in included by document_html_referenced.scss...

I don't know how to fix this properly, as I am not familiar with all of this web complexity.

...

This could also be fixed by:

 .rfcmarkup pre {
   width: 80ch;
   white-space: pre-wrap;
+  overflow: unset;
 }

in document_html_referenced.scss
