"Configuration" example for Groovy Gradle files

Hi,

Is possible to provide an example with "Configuration" but not for .kts Gradle files?

Thanks for a very useful library!

Hello, thanks for this awesome plugin 🎉 !

I too think a sample for configuring the plugin via a groovy build script, would be of great help.
(I would/could contribute a PR for this, if I manage to figure it out 😄 )

The Kotlin DSL classes in the plugin don't lend themselves conveniently for expressing the same thing in Groovy. This is a Groovy conversion of the example in the README.md. Please note that the default rule parameters need to be explicitly specified. I believe adding @JvmOverloads to the rule constructors could mitigate this. The operator overloading unaryPlus is also a problem for Groovy. Here goes:

plugins {
  id 'com.appmattus.markdown' version '0.6.0'
}

import com.appmattus.markdown.rules.config.HeaderStyle
import com.appmattus.markdown.rules.ConsistentHeaderStyleRule
import com.appmattus.markdown.rules.NoDuplicateHeaderRule
import com.appmattus.markdown.rules.SingleH1Rule

markdownlint.with {
    // Optional - Use to override settings for individual rules or add in custom rules
    rules { rb ->
        // Change the default settings of a rule
        rb.unaryPlus(new ConsistentHeaderStyleRule(HeaderStyle.Atx, {rsb -> })) 

        rb.unaryPlus(new NoDuplicateHeaderRule(false, { rsb ->
            // Include files using RegEx for this rule, default=".*" (i.e. all files)
            includes = [".*/directory_to_include/.*"]

            // Exclude files using RegEx for this rule, default=empty (i.e. exclude nothing)
            excludes = [".*/a_file_to_exclude.md"]
        })) 

        // Disable a rule by setting active to false
        rb.unaryPlus(new SingleH1Rule(1, { rsb ->
            rsb.active = false
        })) 
    }   
            
    // Optional - Include files using RegEx for ALL rules, default=".*" (i.e. all files in root project directory)
    includes = [".*/directory_to_include/.*"]

    // Optional - Exclude files using RegEx for ALL rules, default=empty (i.e. exclude nothing)
    excludes = [".*/a_file_to_exclude.md"]

    // Optional - Specify the reports to generate, default=html,checkstyle
    // If you specify the reports block the plugin will output only the types
    // specified i.e. to output no reports implement an empty block
    reports { rb ->
        // enable html report
        rb.html()

        // enable checkstyle xml report
        rb.checkstyle()
    }   

    // Optional - Specify the error count threshold that triggers a failed build, default=0
    threshold = 10
}

Thanks @davidburstromspotify for the helpful comment.

I've been meaning to look into this myself for quite a while! Since I wrote the initial version of the plugin I'm certain there are better ways I can create the configuration that would provide better compatibility for both Groovy and Kotlin DSL.
