Extra spaces and tabs in docstring display fro cucumber adapter for extent version 4.1.x

This is in continuation of this issue https://github.com/extent-framework/extentreports-cucumber4-adapter/issues/60#issuecomment-660677316

Getting 2 spaces for the first line in docstring display using the MarkupHelper.createCodeBlock for extent version 4.1.7. Get an extra tab for versions 4.1.6 and below. In BOTH cases there is an extra new line at the bottom. This works perfectly in extent version 5-snapshot.

Link to the relevant code (docstring branch) with print statements included - https://github.com/grasshopper7/extentreports-cucumber5-adapter/blob/b3a0a6226d831a24bf20f82fad8ab1ac5e6b170f/extentreports-cucumber5-adapter/src/main/java/com/aventstack/extentreports/cucumber/adapter/ExtentCucumberAdapter.java#L463

Will try to update both in a couple of days.

Can u check the wiki. The version number of the klov reporter seems to be missing, instead a maven property placeholder is used. https://github.com/extent-framework/extentreports-java/wiki/KlovReporter

<groupId>com.aventstack</groupId>
<artifactId>klov-reporter</artifactId>
<version>${klov-reporter.version}</version>
