Improve contribution guidelines

[Thiryn]

Description

The contribution guidelines could be improved, as the current guidelines allow to install the provider locally entirely, entering the provider binary hash in the .terraform.lock.hcl which changes at every build. Terraform allows for dev_override for the specific use case of developing a provider, enabling to change the provider without touching the user terraform code.

New or affected resources and data sources

none

Potential terraform configuration
