encoding/json: use zstd compressed testdata

There is a non-public zstd decoder in the stdlib (CL 473356) and
also zstd compressed testdata already present.

Delete testdata/code.json.gz and
instead use internal/jsontest/testdata/golang_source.json.zst,
which has exactly the same content:
	$ cat internal/jsontest/testdata/golang_source.json.zst | zstd -d | sha1sum
	3f70b6fd429f4aba3e8e1c3e5a294c8f2e219a6e  -
	$ cat testdata/code.json.gz | zstd -d | sha1sum
	3f70b6fd429f4aba3e8e1c3e5a294c8f2e219a6e  -

This will reduce the size of the final Go release by 118KB.

Updates #71845
