LG-13107

🛠 Summary of changes

This PR adds/updates the following agencies on the "contact us" form:

• Get.gov
• National Transportation Safety Board (NTSB)
• State of California

A later update was made to the agency NTSB in French with the official State translation.

This PR also adds a hidden form field which was requested by Salesforce. The name of the language/translation of the site (with English, Spanish, and French supported for now) is added to the form field. The technical approach uses Jekyll's Liquid templating language to map the shortened language code to the full language name in English for Salesforce.

Can we rebase / merge main to make sure there's no conflicts with #1237 ? Will this need Chinese translations?

I'll merge main.

This will not need Chinese translations for now, as I do not believe there are versions of the relevant emails in Chinese yet. If the value for the language is empty or invalid for any reason on the Salesforce side (despite an English fallback), the email will be sent in the default language of English.

If Salesforce will default to an English fallback, could we include Chinese anyway? If they add support for it, then we don't have to update here again in the future?
