@teknium1 Tiny docs follow-up to #10549 — just two lines. Adds the Converse API IAM permissions that were missing from the prerequisites, and a link to the CloudFormation deployment template. Should be safe to merge as-is.

Updated — expanded this from 2 lines to 4 fixes across 3 files:

1. IAM permissions in aws-bedrock.md were broken (extra parenthesis, all jammed in one backtick)
2. One-Click Deployment section had literal backslash-n instead of newlines
3. Bedrock missing from quickstart.md provider table
4. Bedrock missing from config.py fallback provider comments

@teknium1 all follow-up to #10549, 9 lines total.

CI status note — all 3 failures are pre-existing, unrelated to this docs-only PR:

• test: 1 flaky test (test_preflight_compresses_oversized_history) — 12103 passed, 1 failed. Not a file we touched.
• docs-site-checks: 11 errors in configuration.md (not modified in this PR).
• check-attribution: contributor email mapping — needs maintainer .mailmap update.
