Greptile Summary

This PR updates the Vertex AI provider documentation prerequisite. The main changes are:

• Adds the Google Cloud IAM role ID for Vertex AI access.
• Changes the displayed role name in the setup step.

Confidence Score: 4/5

This is close, but the role name should be corrected before merging.

• The role ID is useful and points users toward the right permission set.
• The displayed role name can still make IAM role search fail for users following the doc.

### Issue 1 of 1
docs/llm-providers/vertex.mdx:53
**Use Vertex role name** The role ID `roles/aiplatform.user` is correct, but the display name shown here can send users to the wrong IAM search term. In the Vertex AI setup flow, users searching by role name need `Vertex AI User`; searching for `Agent Platform User` can return no matching role even though the ID points to the right permission set.

2. Ensure your account has the `Vertex AI User` role (`roles/aiplatform.user`)

Vertex Role Name Mismatch

This page is for the Vertex AI provider, but the prerequisite now leads with Agent Platform User. A user searching IAM by that display name during Vertex AI setup may miss the expected Vertex AI User role and choose a broader role instead, even though the role ID is correct.

Suggested change

	2. Ensure your account has the `Agent Platform User` role (`roles/aiplatform.user`)
	2. Ensure your account has the `Vertex AI User` role (`roles/aiplatform.user`)
