sshTests fail to apply when source contains a group

[arnecls]

Describe the bug

When submitting an sshTest for a group, the provider returns

Error: invalid character 'I' looking for beginning of value

To Reproduce

Use this snippet with resource "tailscale_acl"

{
    "sshTests": [
        {
            "src": "group:no_ssh",
            "dst": [
                "tag:ssh"
            ],
            "deny": [
                "*"
            ]
        }
    ]
}

Expected behaviour

The snippet should not produce any error.

Desktop (please complete the following information):

• OS: OSX 26.3
• Terraform Version 1.14.4
• Provider Version 0.28.0

Hey @arnecls! I've been able to reproduce this on my end when sshTests is defined but a corresponding groups section is not present in the policy file. Does this align with what you are seeing? Will look into getting some better error messaging around this situation.
