fix(expo): resolve plugin config when registered as bare '@sentry/react-native'

[antonis]

📢 Type of change

• Bugfix

📜 Description

The @sentry/expo-upload-sourcemaps CLI resolves the Sentry org/project/url from the Expo config by scanning the plugins array. It only matched the plugin name @sentry/react-native/expo, so projects that register the plugin under the equally-valid bare name @sentry/react-native were not found — pluginConfig came back null and the script exited 1 with:

🐕 Fetching from expo config...
Could not fetch from expo config, trying sentry.properties files...

Both names resolve to the same plugin module (packages/core/app.plugin.js re-exports ./expo), so the uploader now matches either name.

💡 Motivation and Context

The bare @sentry/react-native plugin path is valid everywhere else in the SDK (config plugin, native build), so the uploader failing on it is an inconsistency, not user error. The only workaround today is registering as @sentry/react-native/expo or setting SENTRY_ORG/SENTRY_PROJECT env vars.

Fixes #6538

💚 How did you test it?

Verified in packages/core/app.plugin.js that both plugin names resolve to the same module, so reading props from a bare-name registration is correct. node --check on the modified cli.js. The change is additive — the existing @sentry/react-native/expo path is evaluated first and behaves identically, and exact-string matching avoids false positives on unrelated packages (e.g. @sentry/react-native-navigation).

📝 Checklist

• I added tests to verify changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• All tests passing.
• No breaking changes.
