Describe the bug

Our getLocaleTimestamp util function is not formatting the timestamp according to the correct locales.

To Reproduce
Steps to reproduce the behavior:

1. Navigate to several pages across translations, e.g:
2. https://ethereum.org/en/eth/
3. https://ethereum.org/de/eth/
4. https://ethereum.org/fr/eth/
5. View the first line of content:
6. https://ethereum.org/en/eth/
   
7. https://ethereum.org/de/eth/
   
8. https://ethereum.org/fr/eth/
   

Across all languages, the timestamp format is the same.

Digging in to the getLocaleTimestamp function, it appears that setting the locale via Moment.js is not working properly:

import moment from "moment"

export const getLocaleTimestamp = (locale, timestamp) => {
  console.log(moment.locale()) // always logs 'en'
  moment.locale(locale)
  console.log(moment.locale()) // still always logs 'en'
  return moment(timestamp, ["ll", "YYYY"]).format("ll")
}

Expected behavior

The display date should be formatted differently depending on the locale.
