refactor(pages): rewrite helpers to output schema in json-ld format

* make sure url are absolutes
* nest breadcrumb schema in webpage schema
* trim HTML tags from content/description
* use a regular script instead of next/script (with the latter the
schema is not updated on route change)
* place the script in document head
* add keywords, wordCount and readingTime keys in BlogPosting schema
* fix breadcrumbs in search page (without query)
* add tests (a `MatchInlineSnapshot` will be better but Prettier 3 is
not supported yet)
