Migrate assets from GCP to AWS

[prashanthakp-setu]

Migrates documentation image/asset URLs from Google Cloud Storage (GCP) to AWS S3. All references to storage.googleapis.com/strapi-assets in the content layer are updated to the new S3 base URL.

What changed
Asset URLs
From: https://storage.googleapis.com/strapi-assets/...
To: https://docs-mdx-assets-sandbox.s3.ap-south-1.amazonaws.com/...

Content
All affected .mdx and .md files under content/ (and README.md) now point to the S3 bucket.

Docs
README.md updated with an Asset Management section that describes:

Bucket name and folder structure
New S3 URL format and examples

How to reference assets in MDX (e.g. with MainImage)
Areas touched

Data: Account Aggregator, DigiLocker, Insights, ULI

Dev tools: Bridge (overview, settings, org-settings, reports, etc.)

Payments: BBPS, BillPay, UMAP, UPI Deeplinks, WhatsApp Collect

Sample content and any other pages that used GCS asset URLs

Notes
Asset hosting is now on the docs-mdx-assets-sandbox S3 bucket (ap-south-1).
No change to doc structure or behaviour; only asset URLs and README instructions were updated.
