fix: Update the quick start flow for AWS Security Hub Integration

[PhaniK-nr]

Summary

We are from SRX team. For our new SRX Cloud feature, we have the integration flow ready Integrate your AWS account whose id is amazon-web-services. We want to add this to the quick start flow of AWS Security Hub Integration whose id is aws-security-hub and thus made the changes accordingly.

• Did you check you NRQL syntax? - Does it work?
• Did you include a Data source and Documentation reference?
• Are all documentation links publicly accessible?
• Did you check your descriptive content for voice and tone?
• Did you check your descriptive content for spelling and grammar errors?
• Did you review your content with a subject matter expert? (e.g. a Browser agent quickstart is reviewed with a member of the Browser Agent team)

Dashboards

• Does the PR contain a screenshot for each of your dashboards?
• Do your screenshots show data?
• Has the sanitization script been run on each dashboard?

Alerts

• Did you check that your alerts actually work?
• Are you trying to create standalone alerts? Standalone alerts are deprecated. They should only be included in quickstarts.
