different versions on the example of libraryDependencies

[marcelo-rosa]

Reading the page

https://docs.scala-lang.org/overviews/scala-book/sbt-scalatest-tdd.html

I saw a conflict in the proposed example in the section Creating the build.sbt file

libraryDependencies ++= Seq(
    "org.scalactic" %% "scalactic" % "3.0.8",
    "org.scalatest" %% "scalatest" % "3.0.8" % "test"
)

and

libraryDependencies ++= Seq(
    "org.scalactic" %% "scalactic" % "3.0.4",
    "org.scalatest" %% "scalatest" % "3.0.4" % "test"
)

I suggest unifying the presented versions so people (like me) that are learning Scala does not get confused about versions 3.0.4 and 3.0.8 in this example. Just pick one of them.

yes, a pull request correcting this would be welcome

incidentally the scalactic dependency isn't necessary, I don't think we should be recommending it to language newcomers. in the test configuration, it's a transitive dependency of scalatest. in the compile configuration, sure it's possible that someone would want to use it, but I think it's really better to recommend the standard, minimum thing which is a single dependency in the test config.

% "test" should be changed to % Test. either will work, but the latter is a little nicer
