Improve documentation on SBT dependencies

[ComFreek]

I had to spend >= 30min to figure out that I needed the following dependencies to run what the docs currently claim to only need finch-circe and 2 imports:

libraryDependencies ++= Seq(
  "com.github.finagle" %% "finchx-core" % "0.31.0",
  "com.github.finagle" %% "finchx-circe" % "0.31.0",
  "io.circe" %% "circe-generic" % "0.12.3"
)

I found the above dependencies in the finch/finch.g8 repo, however a) I had to look in a build.sbt in some sub^n-directory and b) it did not contain versions, so I had to look them up manually on Maven central.

Apparently, #1022 had a very similar issue. There it reads that "Finch is very unfriendly with first time users". Unfortunately, it seems it still is to some extent. Let's improve that 😄

Well, it's been just over three months and this is still the case. Not only that, but the dependencies that @ComFreek do not work anymore.

EDIT:
To get the latest version of Finch, try the following:

val finchVersion = "0.32.1"

libraryDependencies ++= Seq(
  "com.github.finagle" %% "finchx-core"  % finchVersion,
  "com.github.finagle" %% "finchx-circe"  % finchVersion,
)

@baughmann thank you! <3

EDIT:

@baughmann mind to share how to install the lib on a scala3 project (if possible)? 🤔

@well1791 Sorry man, I really haven't been using Scala at all since my last comment
