Fix parameter filtering on qml.data.load_interactive()

[brownj85]

Context:
qml.data.load_interactive() was not actually filtering datasets by the chosen parameters

Description of the Change:

• Rename _interactive_requests to _interactive_request_parameters
• _interactive_request_parameters returns the chosen parameters, which are forwarded to qml.data.load()

Benefits:

• load_interactive() returns only the selected datasets

Possible Drawbacks:

• None

Nice! Looks good to me. 🚀 Should we add a test that catches similar bugs in the future?
Happy to merge once CI tests pass.
