 I18N: Don't use the locale for the HTML language attribute.

 Locales are codes to identify a language in WordPress which can be
 different from the specification for language tags, see
 https://www.w3.org/International/articles/language-tags/.
 An example is `de_DE_formal` or `nl_NL_formal` where the subtag `formal`
 isn't officially supported.

 To give translators the possibility to specify the language tag of their
 language introduce a string `html_lang_attribute` which can be translated
 into the language tag which conforms to the specification.

 Props SergeyBiryukov.
 Fixes #33511.
