Upgrade notes for SimpleSAMLphp 2.3

BC break

• The language codes pt-br and zh-tw have been renamed to pt_BR and zh_TW . Please update your configuration to match the new names.

• Endpoints in metadata (e.g. "SingleSignOnLocation" and "AssertionCosumerService") can no longer be simple strings and are now only accepted in array-style. The old string-style was deprecated for 9 yrs already and was broken anyway. See endpoints for the current format.
