Review Rulesets and add first party Detekt extensions

[TWiStErRob]

Motivation

Got a build failure with Detekt 1.22.0 - TWiStErRob/net.twisterrob.sun#170

* What went wrong:
Execution failed for task ':component:widget:detektReleaseUnitTest'.
> Run failed with 3 invalid config properties.
  	- Property 'style>ForbiddenPublicDataClass' is deprecated. Rule migrated to `libraries` ruleset plugin.
  	- Property 'style>LibraryCodeMustSpecifyReturnType' is deprecated. Rule migrated to `libraries` ruleset plugin.
  	- Property 'style>LibraryEntitiesShouldNotBePublic' is deprecated. Rule migrated to `libraries` ruleset plugin.

changed style to libraries but still got an error:

> Run failed with 1 invalid config property.
        - Property 'libraries' is misspelled or does not exist.

looked for how to include "libraries" ruleset and found nothing.

What's in this PR?

• Update README.md to link to marketplace and give an easy copy-pasteable example for all 3 custom rulesets.
• Add links to their documentation for each marketplace item (if available).
• Document rulesets which are not included by default.
• Review all third party marketplace items and add missing rules.
• Surface unpublished Detekt extensions at the bottom.
• Few smaller fixes

Note: please excuse my React, these are the first lines I've ever written. Might need some touchup.

Even with overflow-y: auto I get this in some cases

what's wrong here?

Are we ok with glitchy scrollbars? It might be a Chrome bug, or just me not knowing the whole CSS structure.

Anyway, probably not worth blocking on this :)

Not a blocker for sure :)

👏🏻 It looks great. And thanks for all the doc updates :)

Still not clear how to avoid this???

        - Property 'libraries' is misspelled or does not exist.

Especially when using the maven plugin, NOT gradle. See my issue — Ozsie/detekt-maven-plugin#169.

This issue states "provide a clear examples", but where can I find them?

Ok, I found this, but it is still not what to add for the maven plugin (is it some configuration or dependency?).

Adding a dependency like this does not help:

    <dependency>
      <groupId>io.gitlab.arturbosch.detekt</groupId>
      <artifactId>detekt-rules-libraries</artifactId>
      <version>${detekt-maven-plugin.version}</version> <!-- is 1.22.0 -->
      <scope>runtime</scope>
    </dependency>

Based on the scope in your above dependency, it's added to the wrong classpath. You added it to the runtime of your code, but it needs to be present on the classpath of the build when the Detekt plugin is executed. I commented on the original issue in the Maven plugin, let's continue there.
