Passing directory arguments results in `Could not get the ContentType` errors since 2.8.0

[silverwind]

Since 2.8.0, this module seems to no longer work when passing directories as arguments:

$ mkdir foo
$ touch foo/bar.txt
$ go run github.com/editorconfig-checker/editorconfig-checker/cmd/editorconfig-checker@2.7.0 foo
$ go run github.com/editorconfig-checker/editorconfig-checker/v2/cmd/editorconfig-checker@2.8.0 foo
Could not get the ContentType of file: bar.txt
stat bar.txt: no such file or directory

[silverwind]

Another related problem is that exit code seems to be 0 with these Could not get the ContentType errors, but I would have expected it to be non-zero when any errors are present.

@silverwind it was likely introduced by me there: #292

327 seems to fix this, you may try it using the commit as below.

$ go run github.com/editorconfig-checker/editorconfig-checker/v2/cmd/editorconfig-checker@a7a8d55e3aaecd1b5f1d4c98df01bc12ccf857b7
