Subject: [PATCH] Revert to using Hugo's own OpenGraph template

I had overridden Hugo's OpenGraph template to improve it, but those
changes have been upstreamed in Hugo 0.19. We can use theirs now.

See: https://github.com/spf13/hugo/pull/3073

-<!--
- Import of internal opengraph template from Hugo's `tpl/template_embedded.go`
- until site authors and social metadata can be standardized[0]. Meanwhile, I
- wanted to work on better usage of Twitter and Facebook OpenGraph tags[1][2].
-
- First, because the .Site.Authors wiring doesn't work yet, several date-related
- tags never get used, and also to correct the logic on these tags:
-   - All nodes/pages should use this metadata (it currently depends on .Site.Authors and .Social.Facebook)
-   - Published time should be flexible and use EITHER publishdate or date from frontmatter
-   - Modified time should use .Lastmod, which can use enableGitInfo and falls back seamlessly to .Date
-   - Nodes should use type "website" and og:updated_time
-   - Pages should use type "article" and article:modified_time
-
- Several Twitter-related fields are incorrectly used:
-   - Site-specific Twitter account
-   - User-specific Twitter account
