Use name attribute instead of property for Twitter meta tags?

[tannerdolby]

Open Graph protocol also specifies the use of property and content attributes for markup (<meta property="og:image" content="http://example.com/ogp.jpg"/>) while Twitter cards use name and content. Twitter’s parser will fall back to using property and content, so there is no need to modify existing Open Graph protocol markup if it already exists.

While Open graph meta tags use the property and content attributes, the Twitter card docs state they use name and content. Should these Twitter card meta tags use name instead of property? There might be a reason for keeping these twitter meta tags with property attributes (https://stackoverflow.com/questions/22350105/whats-the-difference-between-meta-name-and-meta-property)

for instance in base.njk L35-L43 these property attributes for twitter card metadata could be changed to name (unless they were explicitly defined with property attributes for a reason)

<!-- Twitter -->
<meta property="twitter:card" content="summary_large_image">
<meta property="twitter:site" content="@eleven_ty">
<meta property="twitter:creator" content="@zachleat">
<meta property="twitter:url" content="https://www.11ty.dev/">
<meta property="twitter:title" content="{{ subtitleText }}">
<meta property="twitter:description" content="{{ social.description }}">
<meta property="twitter:image" content="{{ social.imgsrc }}">
<meta property="twitter:image:alt" content="{{ social.imgalt }}">
