Write an attribution config file

Set attribution config strings for French and English. If the input
email's body language is in French, set my French attribution string.
Otherwise use English.

Write the attribution string to a config file at
`~/.local/share/ottolangy/attribution.muttrc`. We can then source this
config file to set the attribution.
