Error: Holidays in France are not currently supported!

I'm using R and want to fetch built-in country holidays for France. I tried the below:

```
fit_prophet <- add_country_holidays(fit_prophet, country_name = "FR")
fit_prophet <- add_country_holidays(fit_prophet, country_name = "FRA")
fit_prophet <- add_country_holidays(fit_prophet, country_name = "France")
```
but I'm getting this error -> `Holidays in FR are not currently supported!`

According to the below documentation of `holidays` Python package, from where Prophet fetches the country holidays, France is included with `FR` or `FRA` country codes.

What can I do to resolve this?
