Description

Looking at the output from Array.info, I'm noticing that we are not showing the name of the codecs. This seems like an important bit of information that should be part of the output of info.

Steps to reproduce

import zarr
import numpy as np

# Create a 2D Zarr array
z = zarr.create_array(
   store="data/example-1.zarr",
   shape=(100, 100),
   chunks=(10, 10),
   dtype="f4"
)

# Assign data to the array
z[:, :] = np.random.random((100, 100))
z.info

Type               : Array
Zarr format        : 3
Data type          : DataType.float32
Shape              : (100, 100)
Chunk shape        : (10, 10)
Order              : C
Read-only          : False
Store type         : LocalStore
Codecs             : [{'endian': <Endian.little: 'little'>}, {'level': 0, 'checksum': False}]
No. bytes          : 40000 (39.1K)

Additional output

will users creating arrays with create_array know what codecs means? see #2633

Perhaps not, but we can teach them. But regardless of how we present it, we should include the name of the thing (e.g. zstd, blosc, etc.).
