[BUG] AKVS not removing any keys/values deleted in Key Vault after sync

[abh07054]

We are using Multi Key Vault Secret from Azure Key vault

In first version the content is given as
{
"test1": "dGVzdAo=",
"test2": "dGVzdAo="
}

In second version the content is given as
{
"test1": "dGVzdAo=",
"test2": "dGVzdAo="
"test3": "dGVzdAo=",
}

AKVS was able to sync to output as secret until now but after some time we deleted test3 key value and we made it as first version in key vault. but the key test3 still exists in secret even after sync.
