How to add a new version to ping/go

When a new version of libp2p is released, we want to make it permanent in the ping/go test folder.

In the ping/_compositions/go-cross-versions.toml file,
- Find the group for the latest version (v0.20 for example) and copy it into a new group (v0.21 for example).
- Update the selectors (go tags) and modfile options. Update the build_base_image if needed.
In the ping/go folder,
- Add a new compatibility shim in compat/ if needed, or add your new selector to the latest shim (see compat/libp2p.v0.17.go for example).
- Create the new mod and sum files (go.v0.21.mod for example). Assuming you're updating from v$A to v$B, a simple way to do this is to:
  - cp go.v$A.mod go.v$B.mod; cp go.v$A.sum go.v$B.sum
  - ln -s go.v$B.mod go.mod; ln -s go.v$B.sum go.sum (you may also use this for local development, these files are ignored by git)
  - update the go-libp2p version, go version, and update the code if needed.
  - then go get -tags v$B && go mod tidy
