feat: Adds a prepare target to makefile

Adds a prepare target to makefile to globally replace instances of `xyz` and `abc`.
This should make it easier for users to get started.
This is similar to what is done in pulumi-tf-provider-boilerplate.

It skips the sdk and examples directory to illustrate what needs to be changed initially.

+
+    ```bash
+    make prepare NAME=foo REPOSITORY=github.com/pulumi/pulumi-foo ORG=myorg

+   - replace dependencies in `provider/go.mod` to reflect your repository name
+   - find and replace all instances of the boilerplate `xyz` with the `NAME` of your provider.
+   - find and replace all instances of the boilerplate `abc` with the `ORG` of your provider.
+   - replace all instances of the `github.com/pulumi/pulumi-xyz` repository with the `REPOSITORY` location
