Update ipAsset.ts

[cypherpepe]

Modified the mintAndRegisterIpAndMakeDerivative function to include the return of tokenId, similar to the behavior in mintAndRegisterIpAssetWithPilTerms. This ensures consistency across functions that involve IP registration and minting.

Description

• Added the tokenId to the return statement in mintAndRegisterIpAndMakeDerivative.
• This change brings parity with mintAndRegisterIpAssetWithPilTerms by ensuring both methods return the tokenId.

Test Plan

• Validate the functionality by minting an IP and ensuring the response includes the tokenId.
• Conduct tests with different IP and derivative data to confirm the new return structure.
