@W-20452321: Migrate AWS SDK V2 to V3

[o-olaosebikan]

Migrate AWS SDK FROM Version 2 TO Version 3

Description

End of life support FOR AWS-SDK was reached on September 8, 2025

The JS AWS SDK is used to send metrics to cloudwatch from pwa kit runtime library. The goal is to update the library to use v3 version. We utilize codemod scripts for the migration (recommended by AWS) and manually adjust discrepancies between the two versions

Followed test instructions, seeing metrics as expected from a bundle built from this branch 🙌 📈 . Happy to approve review once you address the nit above.

The one failing check I'm seeing from CI right now (SalesforceCommerceCloud/pwa-kit/test / pwa-kit-windows (22, 8) (pull_request)) seems unrelated to your change.

Looking good, CI happy 👍
