Please describe your feature request.
Inverse operator of contains, probably called in or something alike?

Describe the solution you'd like
If we have data1.yml like:
(please keep to around 10 lines )

- {item: 'Pizza', type: 'Food'}
- {item: 'Pasta', type: 'Food'}
- {item: 'Rose', type: 'Flower'}
- {item: 'Tulip', type: 'Flower'}
- {item: 'Hammer', type: 'Tool'}
- {item: 'Screwdriver', type: 'Tool'}

And we run a command:

yq 'filter(.type | in(["Tool", "Food"]))' data1.yml

it could output

- {item: 'Pizza', type: 'Food'}
- {item: 'Pasta', type: 'Food'}
- {item: 'Hammer', type: 'Tool'}
- {item: 'Screwdriver', type: 'Tool'}

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

yq 'filter(.type as $el | ["Tool", "Food"] | contains([$el]))' data1.yml

Additional context
jq also has the in operator
