feat: upgraded to thew new terrafrom plugin framework 1.x

[mridang]

This pull request upgrades the terraform-plugin-framework dependency from version 0.15.0 to the latest version 1.17.0. This update replaces a deprecated three-year-old framework version to ensure the provider remains maintainable and compatible with modern Terraform standards. The changes include necessary refactoring of resource definitions, schema generation, and state management logic to align with the significant API changes introduced between these versions.

Closes #231
