Build the OpenGraph locale meta tag block — one canonical
og:locale for the current language plus an og:locale:alternate
for every other supported language. Emitting the alternates lets the
Facebook/LinkedIn crawler discover the localized siblings without
having to follow the <link rel="alternate" hreflang> chain.
The output is intentionally indented with two spaces to match the
surrounding <head> formatting in the four generators.
Parameters
currentLang: string
Language being rendered (drives og:locale)
Returns string
Multi-line HTML fragment ready to drop into <head>
