[Feature] Make YAML wildcard support "k: v" pairs

[PurplefinNeptuna]

Currently this is not supported. sorry for dirty examples: I usually use them like __boob/*/*__

What is the meaning of that?

[PurplefinNeptuna]

currently the wildcard only accepting dictionary values as list or dictionary, not a string example:

# Key contain a list is working
A:
  - B
  - C

# Key contain dict is also working
A:
  B:
    - C
  D:
    - E

# But if the key's value is a string, it doesn't work
A: B

# This also doesn't work
A:
  B: C

# Both example above are valid YAML, but not working as wildcard YAML

This is implemented.
