Update to rn0.83

[sunitaprajapati89]

Amazon Vega SDK 0.24 adds React Native 0.83 support. Existing Vega apps on
RN 0.72 will migrate to RN 0.83, and the current
@segment/analytics-react-native-plugin-kepler (v1.0.0) pins Amazon
dependencies on the RN 0.72 line. Update the plugin's @amazon-devices/*
dependencies and RN toolchain to the RN 0.83 line, verify against Vega SDK
0.24, and publish a new version to npm so Segment support is available for
Vega apps on RN 0.83.

IMPORTANT: Do not modify the version currently consumed by RN 0.72 Vega
apps. Bump the version number and publish a new release; existing RN 0.72
apps migrate on their own timeline.

BACKGROUND

The plugin provides Segment analytics for Amazon Vega RN apps. It wires
Vega-specific providers into the core SDK: deviceInfoProvider
(@amazon-devices/react-native-device-info + -localize), storePersistor
(Amazon's AsyncStorage fork), and KeplerUUIDProvider.

The @amzn/* -> @amazon-devices/* namespace migration is already complete
in the current source; no namespace work remains.

@amazon-devices/* packages are published to public npm; no .npmrc auth
token is required.

Related prior art: analytics-react-native/notes/rn-upgrade.md documents
the core SDK's RN 0.84 / New-Architecture upgrade. Many toolchain changes
(babel preset, metro config, gradle) apply to this 0.83 bump.

FILES TO CHANGE (analytics-react-native-plugin-kepler)

package.json -- peerDependencies (lines ~48-54) and overrides
(lines ~56-58) for all four Amazon packages above.

package.json devDependencies -- bump RN toolchain 0.72 -> 0.83:
react-native (^0.72.0), @types/react-native (0.72.6); swap
metro-react-native-babel-preset -> @react-native/babel-preset; bump
react-native-builder-bob, @react-native/eslint-config, and
react / @types/react as needed for 0.83.

example/package.json -- bump react-native (0.72.0 -> 0.83.x), the three
@amazon-devices/* deps + async-storage alias, and the kepler/CLI tooling
to the Vega SDK 0.24 line.

Evaluate bumping the @segment/analytics-react-native peer/dev dependency
from the pinned pre-release 2.20.0-beta.2 to the current core release
(2.21.4).

Bump plugin version and publish a new npm release.

ACCEPTANCE CRITERIA

[ ] Plugin package.json peer deps + overrides updated to the RN 0.83
versions above.

[ ] Plugin builds cleanly (bob build); tsc --noEmit and tests pass on the
RN 0.83 toolchain.

[ ] Example app builds and runs on Vega SDK 0.24 (RN 0.83); events reach
Segment -- verify track/identify, deviceInfoProvider, storage
persistence, and UUID generation.

[ ] New plugin version published to npm; version bumped, existing RN 0.72
release untouched.

[ ] README updated if any install/usage steps change for RN 0.83.

NOTES / RISKS

Known plugin limitations remain (per README):
react-native-device-info returns unknown/empty for some context fields;
trackDeepLinks and native anonymousId unsupported. Re-check whether
device-info 2.1.9...-rn-83 fills any hardcoded TODO fields in
src/device-info.ts (networkType, screenHeight, screenWidth).

The -rn-83 version suffixes are Amazon early-access build identifiers and
may change before GA -- confirm final published versions on npm before
publishing.

RN 0.72 -> 0.83 is a large jump; expect babel/metro config churn in the
example app. Reuse patterns from notes/rn-upgrade.md.
