go-ipld-prime/codec/json may panic if asked to encode bytes

Description

`go-ipld-prime` is a series of Go interfaces for manipulating IPLD data and a Go module that contains the `go-ipld-prime/codec/json` codec. ### Impact Encoding data which contains a `Bytes` kind Node will pass a `Bytes` token to the JSON encoder which will panic as it doesn't expect to receive `Bytes` tokens. Such an encoding should be treated as an error, as plain JSON should not be able to encode Bytes. **This only impacts uses of the "json" codec, "dag-json" is not impacted.** Use of "json" as a decoder is not impacted. ### Patches Fixed in v0.19.0. ### Workarounds Prefer the "dag-json" codec which has the ability to [encode bytes](https://ipld.io/specs/codecs/dag-json/spec/#bytes). ### References See fix in [#472](https://github.com/ipld/go-ipld-prime/pull/472)
