Release v0.5.0

[bpholt]

Release v0.5.0

• Merge Update refined, refined-scalacheck to 0.11.3 #291

• Prepare release in this repo

• Make PR to Scala Steward to make it aware of our Scalafix

  I think it will look like adding this

  {
    groupId: "org.dwolla",
    artifactIds: ["fs2-pgp", "pgp-testkit"],
    newVersion: "0.5.0",
    doc: "https://github.com/Dwolla/fs2-pgp#scalafix-rule",
    rewriteRules: ["dependency:com.dwolla.security.crypto.V04to05@com.dwolla::fs2-pgp-scalafix:0.5.0"]
  }
  

  to scalafix-migrations.conf, but I'm waiting for feedback in Discord on a couple things.
