[Federation] Remove long language tags citation from OpenID Connect Core 1.0, section 5.2.

[Vladimir Dzhuvinov]

Section 11 has a long verbatim citation from OIDC Core regarding the use of language tags.

This is a proposal to remove the citation and simply rely on the reference at the top of the section. Another argument to remove the long citation is that portions of OIDC Core may change with errata, so it’s best to reference rather than copy text 1:1.

[Vladimir Dzhuvinov]

Section 11 will also need a slight rewrite to reflect the fact that language tags can appear in metadata parameters besides ES and EC claims.

Yes, we should do these things.
