👷 Sync rum-events-format schemas for session replay image content

[BeltranBulbarellaDD]

Motivation

Synchronize the Browser SDK with the latest rum-events-format schema so session replay can represent image content changes and resource IDs consistently.

Changes

• Bump @datadog/rum-events-format to the schema revision containing:
  • ImageContentChange session replay changes.
  • StringResourceId string role.
  • WASM stack-trace symbolication fields.
• Regenerate the schema-derived TypeScript types.
• Add the corresponding SDK ChangeType.ImageContent and StringRole.ResourceId constants.
• Update string ID handling and change encoding/decoding for image resource IDs.
• Add a decoder regression test for image content resource references.

Test instructions

Run:

yarn typecheck
yarn test:unit --spec packages/browser-rum/src/domain/record/encoding/changeDecoder.spec.ts
