fix(html-validator): skip /_og/ prerender routes

nuxt-og-image signs OG URLs like /_og/s/o_*.png under strict mode. The
intermediate HTML render Nitro hands to prerender:generate has a .html
fileName, so @nuxtjs/html-validator validates it against all rules,
including long-title, which fails because the OG page inherits the source
page's full title (routinely >70 chars).

The module's `ignore` option is dev-mode only — there's no prod hook to
opt out, so patch the check at module.mjs:98 to early-return for routes
starting with /_og/.
