fix(files_sharing): Fix FileList account filter button translation

[falghamdi125]

Summary

This is a simple fix to FileListFilter translation so it gets the People button translation in the file list filter from the correct source. Currently, the files_sharing app tries to get the account filter button from 'files' app but the needed string is added to files_sharing locale files.
