.Label() and .Child() for types panic on some map types

[czunker]

Describe the bug
We experienced a panic in the backend, when trying to call .Label() or .Child() on a map.

The panics happened here:
https://github.com/mondoohq/cnquery/blob/main/types/types.go#L271
and
https://github.com/mondoohq/cnquery/blob/main/types/types.go#L224

The resource which triggered this was most likely logindefs.params.
Strange is, the resource is defined as map[string]string:

cnquery/providers/os/resources/os.lr

Line 1036 in 3fd1be3

params(content) map[string]string

But created as map[string]interface:

cnquery/providers/os/resources/logindefs.go

Line 62 in 3fd1be3

res := make(map[string]interface{})

To Reproduce
Steps to reproduce the behavior:

1. I'm not sure how to replicate this with cnquery directly.

Expected behavior
No panic.

Desktop (please complete the following information):

• cnquery v11.2.0 and os provider 11.1.0
