build: remove webdriver-binaries-gradle-plugin

[sdelamo]

The webdriver binary plugin was useful to ease running the Web tests with real browser but we can get rid of it.

It currently fails with:

> Failed to apply plugin class 'io.micronaut.build.docs.JavadocAggregatorPlugin'.
   > A problem occurred configuring project ':test-suite'.
      > Could not resolve all files for configuration ':test-suite:classpath'.
         > Could not find org.ysb33r.gradle:grolifant:0.5.1.
           Searched in the following locations:
             - https://plugins.gradle.org/m2/org/ysb33r/gradle/grolifant/0.5.1/grolifant-0.5.1.pom
             - https://repo.maven.apache.org/maven2/org/ysb33r/gradle/grolifant/0.5.1/grolifant-0.5.1.pom

@sdelamo 🤔 Too slow...

I think we can also do this:
