Docs Hugo minor issues

[XhmikosR]

Looking good. couple of minor quick things I noticed:

• The code syntax highlighting is not quite as good imo:
  https://getbootstrap.com/docs/4.5/getting-started/javascript/#sanitizer
  https://deploy-preview-32077--twbs-bootstrap.netlify.app/docs/4.5/getting-started/javascript/#sanitizer
  Maybe just need to add blue color: #006ee0 to class .nx ?

• Looks like an unnecessary extra line break at bottom of the browser list here:
  https://deploy-preview-32077--twbs-bootstrap.netlify.app/docs/4.5/getting-started/browsers-devices/#supported-browsers

I'll try to fix these issues tomorrow; the extra line break one is lower prio, though, but I'd like to update/revisit the syntax highlighting styles.

Going to close this. If anyone wants to report any discrepancies, they are more than welcome :)
