fix(core): allow i18n.localeConfigs.translate in validation

[trofim24]

Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
• If this is a new API or substantial change: the PR has an accompanying issue (closes i18n.localeConfigs.translate isn't accepted by validation #11451) and the maintainers have approved on my working plan.
