Feature request

Based on the documentation here:

https://developer.hashicorp.com/terraform/plugin/log/writing

We should consider migrating all instances of log.Printf to tflog for improved structured logging and better integration with Terraform's logging system.

This would allow us to use log levels, context-aware logging, and improve debugging capabilities, aligning with new best practices for Terraform provider development.
