Include SBT plugins as dependencies

[MPV]

Does this support including SBT plugins as dependencies?

Over in #138 @adpi2 said:

This Github action submits the snapshot of all the dependencies downloaded by the build: the compile dependencies, the test dependencies, the scala tools (compiler and scaladoc), and their transitive dependencies, for all Scala versions and platforms.

We've seen this working, but are missing SBT plugins when using this action.

What are your thoughts on adding support for this?

Here's a concrete example:

$ cat project/plugins.sbt
addSbtPlugin("org.xerial.sbt"            % "sbt-pack"      % "0.17")
addSbtPlugin("ch.epfl.scala"             % "sbt-scalafix"  % "0.11.1")
addSbtPlugin("io.github.davidgregory084" % "sbt-tpolecat"  % "0.4.4")
addSbtPlugin("org.scoverage"             % "sbt-scoverage" % "2.0.9")

It would be great, but I have not yet found a good way to implement it.
