docs: Update suggested source of IAM samples (googleapis#13666)

glasnt · web-flow · commit 9b5ba99b6e8a · 2025-03-17T07:17:11.000-04:00
The README originally pointed to a PR that only adds deny-based samples, and not actually linking the base folder. I experienced friction when discovering this link (originally from the docs link in https://cloud.google.com/python/docs/reference/iam/latest#code-samples-and-snippets), thinking that there were no Python IAM role/service related snippets (only Deny), but then finding the folder the PR added to full of samples.
