closes #9569 - Removed the `<1 min read` time clause, effectively making `1 min read` the minimum reading time - Removed the `seconds` option for i18n strings, which contained the less than one minute display string - Kept the other i18n string options the same - Amended and improved tests for new functionality

// # Reading Time Helper
|
|
//
|
|
// Usage: `{{reading_time}}`
|
|
// or for translatable themes, with (t) translation helper's subexpressions:
|
|
// `{{reading_time seconds=(t "< 1 min read") minute=(t "1 min read") minutes=(t "% min read")}}`
|
|
// and in the theme translation file, for example Spanish es.json:
|
|
// "< 1 min read": "< 1 min de lectura",
|
|
// "1 min read": "1 min de lectura",
|
|
// "% min read": "% min de lectura",
|
|
//
|
|
// Returns estimated reading time for post
