deleteValueAtPath path dict

deleteValueAtPath modifies dict to delete the value at path and returns dict. path can be either a string containing a .-separated list of keys or a list of keys.

If path does not exist in dict then deleteValueAtPath returns dict unchanged.

!!! example

```
{{ dict "outer" (dict "inner" "value") | deleteValueAtPath "outer.inner" | toJson }}
{{ dict | setValueAtPath "key1" "value1" | setValueAtPath "key2.nestedKey" "value2" | toJson }}
{{ dict | setValueAtPath (list "key2" "nestedKey") "value2" | toJson }}
```
