acorn secret reveal -o json has incorrect values.

[sangee2004]

acorn version v0.7.1-15-g167b9f5e+167b9f5e

Steps to reproduce the problem:

1. Create a secret

 acorn secret create --data test1=value1 --data test2=value2 mytestsec

2. Use acorn secret reveal to reveal the secret.

 % acorn secret reveal mytestsec        
NAME        TYPE      KEY       VALUE
mytestsec   opaque    test1     value1
mytestsec   opaque    test2     value2

3. Use acorn secret reveal -o json to reveal the secret. Notice that there are 2 entries returned . Each entries has details of both keys test1 and test2. The values are incorrect in one of them and empty in the other entry.

acorn secret reveal mytestsec -o json

        {

    ]
}

Regression introduced by #1806

1. "Wrong" values because it's now printing the plain Secret Objects, with values not decoded
2. Duplicate entry, because it's printing on a loop over the included keys

Question is if we actually want to have the raw object output here.
--> Answer: Yes, but with data decoded

Tested with acorn version v0.8.0-alpha7-98-gbb130866+bb130866

acorn secret reveal -o json works as expected.

acorn secret reveal mytestsec -o json 
{
    "items": [
        {
            "kind": "Secret",
            "apiVersion": "api.acorn.io/v1",
