Enhance Makefile for building and managing Terraform provider

- Update provider version to 0.2.1
- Automatically determine OS and architecture using `go env GOOS` and `go env GOARCH`
- Define variables for plugin directory and output path
- Add commands for building, testing, formatting, linting, and cleaning the project
- Include command to install dependencies using `go mod tidy`
- Add help command to display usage information

This update improves the Makefile by making it more flexible and adding useful development commands.
