fix: tryParse line-length to int when it's not already an integer

[jkoenig134]

Description

The flag --line-length was added, but it seems like it doesn't work as ArgParser doesn't seem to transform this param to int by default. This fix takes the String argument and tries parsing it to an int.

@spydon I think the main issues why this occurred is that #689 didn't add a test. For protecting this command for regression issues I'm totally with you, I am open looking into the testing and adding tests for this.

@jkoenig134 thank you! I tried to add a test, but it didn't work.

I just made the following modification and was able to confirm that it works correctly at hand.

    final lineLength =
        switch (int.tryParse(argResults?['line-length'] as String)) {
      final int length => length,
      _ => null,
    };

@spydon added the test

@spydon as a follow-up i would really like to add setExitIfChanged and lineLength to the config.

I am mostly though with that. As it is not only a Bugfix - can I PR this?
