Allow inline code blocks

I've seen a couple of places where CiviCRM core is using <code> within <p> tags. Currently code is always display: block which looks a bit odd:

civicrm/admin/setting/url:

System status:

I suggest adding:

.crm-container p code {
  display: inline-block;
}

I can open a PR, but wanted to open the issue first before I forget.
