Release v0.8.0

[guseggert]

• Verify your GPG signature is configured in local git and GitHub
• Ensure Boxo and Kubo are checked out on your system
• Create a release branch called release-vX.Y.Z and push it
  • Use master as base if Z == 0
  • Use release as base if Z > 0
• Tidy the changelog and push any changelog changes to release-vX.Y.Z
• Create a draft PR merging release-vX.Y.Z into release
• If Z > 0, then cherry-pick the necessary commits from master into release-vX.Y.Z using git cherry-pick -x <commit>
• Ensure Boxo tests are passing
• Ensure Kubo tests are passing
  • Go to Kubo dir and run go get github.com/ipfs/boxo@<commit_hash> using the commit hash of the release-vX.Y.Z branch
  • Run go mod tidy in repo root and in docs/examples/kubo-as-a-library
  • Commit the changes and open a draft PR in Kubo
  • Paste a link to the Kubo PR in the Boxo PR, so reviewers can verify the Kubo test run
  • Verify the CI passes
• Add a commit in release-vX.Y.Z bumping the version in version.json to vX.Y.Z
• Add a "release" label to the Boxo PR
• After the release checker creates a draft release, copy-paste the changelog into the draft
• Wait for approval from another Boxo maintainer
• Merge the PR into release, using "Create a Merge Commit", and do not delete the release-vX.Y.X branch
  • Verify the tag is created automatically by the releaser action
• Create a PR merging release into main
• Create the GitHub release

One todo we don't want to forget: this needs to change to v0.8.0:

boxo/cmd/boxo-migrate/boxomigrate.go
