refactor tool env

[bboynton97]

Currently when you add a new tool, in <tool_name>.json, you have an env property.

{
    "name": "agent-connect",
    "package": "poetry add agent-connect",
    "env": "HOST_DOMAIN=...\nHOST_PORT=\"80\"\nHOST_WS_PATH=\"/ws\"\nDID_DOCUMENT_PATH=...\nSSL_CERT_PATH=...\nSSL_KEY_PATH=...",
    "tools": ["send_message", "receive_message"]
}

this is too rigidly designed. instead, lets accept a list of strings and handle the new line in the code. instead, this should look like

{
    "name": "agent-connect",
    "package": "poetry add agent-connect",
    "env": 
        [
            "HOST_DOMAIN",
            "HOST_PORT=\"80\"",
            "HOST_WS_PATH=\"/ws\"",
            "DID_DOCUMENT_PATH=...",
            "SSL_CERT_PATH=...",
            "SSL_KEY_PATH=..."
        ],
    "tools": ["send_message", "receive_message"]
}

change the current tool configs to match
