[IT-4483] Refactor get_synapse_owner_id

[zaro0508]

Refactor get_synapse_owner_id method to get the owner ID from both synapse::ownerId and aws:servicecatalog:provisioningPrincipalArn tags with the former as the preferred option and the latter as the fallback option.

This implements the following proposal in IT-4483:

For a SC product Updates action the lambda currently also gets the synapse id
from the aws:servicecatalog:provisioningPrincipalArn tag.  We would need to
refactor the lambda to get the synapse id from thesynapse:owerId tag instead.
Then the lambda will generate and apply all of the synapse prefixed tags with the
new owner info.

Pull Request Overview

Refactor the get_synapse_owner_id method to prioritize the synapse:ownerId tag over the aws:servicecatalog:provisioningPrincipalArn tag, providing a fallback mechanism for owner identification.

• Updated function logic to check for synapse:ownerId first, then fall back to extracting ID from the provisioning principal ARN
• Changed error handling from raising ValueError to returning None when no valid tags are found
• Enhanced input validation with proper TypeError for unsupported input types
