bugfix update column with Unicode comment

When we crete column with unicode comment, annotate gem does not update that annotation.

`\w` means a word character([a-zA-Z0-9_]) and it does not match unicode
leteers.
https://docs.ruby-lang.org/en/3.0.0/Regexp.html

Now `column_pattern` in `annotante_one_file` support
ascii characters only and doesn't match column with unicode comment.
So the columns will disappear from `old_columns` and `new_columns`.

https://github.com/ctran/annotate_models/blob/786394947c041f781df2ee0ea003e09452fa9dba/lib/annotate/annotate_models.rb#L378-L380

Even if we change that column (i.e. nullable to not null),
annotate_one_file's check ignore that column so annotation doesn't
update.
(The first time create it, it works, and the column annotation is left out of date)

So I fix column_pattern support unicode letter.
