Promote offcanvas variables to :root theme files and document in CSS Variables tab

- Move --offcanvas-* definitions from component-scoped .offcanvas selector in
  template.css into :root[data-bs-theme] blocks in light.standard.css and
  dark.standard.css so they are overridable via user.css at root level
- Fix two bugs in the old definitions: --offcanvas-bg was incorrectly set to
  var(--body-color) (text colour); corrected to var(--body-bg); and
  --offcanvas-color had a spurious 'color:' prefix
- Dark theme uses a heavier box-shadow (0.3 alpha) for better depth perception
- Add css_vars_offcanvas field to templateDetails.xml CSS Variables tab
- Add en-US and en-GB language strings for the new Offcanvas Panel section
- Rebuild all .min CSS files
