Add social media previews, sharing links to canvasses and page metadata

[sammeltassen]

Currently the meta tags are the same for any page. Previously the page or object title was used in combination with a thumbnail of the object. It was also possible to link to specific pages as follows:

https://heritage.tudelft.nl/nl/objects/tresorleeszaal-839007461?id=10

This would not generate a preview of the specific canvas when sharing, since this would require SSR. Perhaps Netlify's Service Workers could be used to make this possible.

Adding to this:

Replace the current meta tags for the actual page title and description (if available) and add open graph tags
