Proper types for all inputs

[gabrieljones]

Describe the bug
Proper types for all inputs.
Different inputs contexts have different sets of supported types.
Lack of array or object types.
Impairs workflow composability, maintainability, and security.

To Reproduce

workflow_call supports type with boolean, number, or string
workflow_dispatch supports type with boolean, choice, number, or string
Action inputs: no types at all

Expected behavior
Same set of supported types for all inputs contexts.
Add array and object types.
