* Fix canonical link tag to point to correct PEP URL
* Use shorter, standard HTML5 syntax for self-closing tags
* Avoid depr clip prop & use better supported transform prop in CSS
* Use strict mode in the color scheme JS
Since the basic admonition admonition styles are just applied to a couple individual admonitions, rather than admonitions in general, those other than "warning" and "note" won't display as admonitions at all. In addition to fixing that, this PR adds appropriate, standard colors for each of the additional admonition types in both light and dark mode.
* Infra: remove one of the four instances of title at top of pages
* Infra: remove another of the five instances of title at top of pages
* Infra: but keep PEP number in the breadcrumbs
