Invalid escape characters in intellijreport.json

[lars-reimann]

Kover version: 0.4.3
Coverage Engine: IntelliJ with default version
OS: Windows

---

Minimal build.gradle.kts:

plugins {
    id("org.jetbrains.kotlinx.kover") version "0.4.3"
}

repositories {
    mavenCentral()
}

kover {
    coverageEngine.set(kotlinx.kover.api.CoverageEngine.INTELLIJ)
    generateReportOnCheck.set(true)
}

When running ./gradlew check on Windows I get the following output:

> Task :[REDACTED]:koverHtmlReport FAILED

Arguments must be passed in the following JSON format:
{
  "modules": [
    { "reports": [
        {"ic": "path to ic binary file", "smap": "path to source map file"}
      ] [OPTIONAL, absence means that all classes were not covered],
      "output": ["outputRoot1", "outputRoot2"],
      "sources": ["sourceRoot1", "sourceRoot2"]
    }
  ],
  "xml": "path to xml file" [OPTIONAL],
  "html": "path to html directory" [OPTIONAL]
}

FAILURE: Build failed with an exception.

This is the content of intellijreport.json:

{
  "html": "[REDACTED]\build\reports\kover\html",
  "modules": [
    { "reports": [ 
        
      ], 
      "output": [
        
      ],
      "sources": [
        
      ]
    }
  ]
}

I guess the \ in the html property should be replaced by \\.

Jacoco works with 0.4.3, though, which is already workable.

@lars-reimann, please check in 0.4.4

[lars-reimann]

0.4.4 works, thank you very much.
