(MODULES-2071) Refactor file_line provider to contain logic to handle parameter multiple in function handle_create_with_after
Without this, file_line resource without the `match` parameter but with the `after` param will throw an error if there are multiple matches for the after expression. This patch creates the handling for the `multiple` parameter in handle_create_with_after. This allows you to add a line after the `after` expression if it appears at multiple points in a file. Updated reference to `file_line` in the README to reflect that the multiple parameter can be set when using `after` and/or `match` as the matching regex.
