David Allison aa062db4e0 fix: Remove noise from ktLintformat output
A user would struggle to determine what the error was if `ktLintFormat`
failed

`-q` (error only) is overkill as it removes useful output,
but there is a large amount of warnings in the current
version of the ktLint plugin

GitHub ref: JLLeitschuh/ktlint-gradle/issues/457

This can be converted to `-w` (warnings only) afterwards

A typical error is:

```
 KtLint found code style violations. Please see the following reports:
     - C:\\...\ktlintTestSourceSetFormat\ktlintTestSourceSetFormat.txt
```

After adding `-w`, we'd also get the more useful:

```
CriticalExceptionTest.kt:19:1 Wildcard import (cannot be auto-corrected)
```
