Draft: configuration options

refreshVersions has configuration options that are documented (well) in the docs

See https://jmfayard.github.io/refreshVersions/setup/#configure-the-plugin

Draft documentation:

refreshVersions {
    // Usage: if you use versions catalog, you can put both files in the same folder
    versionsPropertiesFile = file("gradle/versions.properties")

    // See https://jmfayard.github.io/refreshVersions/gradle-buildsrcversions/
    enableBuildSrcLibs()

    // Use case: code we merge in main but is not ready for general consumption yet
    featureFlags {
        enable(LIBS)
        disable(GRADLE_UPDATES)
    }

    // Define your own rules
    // See also: Simpler API for configuring simple rules https://github.com/jmfayard/refreshVersions/issues/580
