fix(typos): run with '--force-exclude' (#394)

This commit forces typos to ignore files explicitly passed as cli
arguments, if they would otherwise be ignored based on typos' config.
Previously, treefmt could explicitly pass files to typos that typos
should otherwise ignore, which is expected behavior to typos but is not
desirable when working with treefmt.
