Expo Updates: add tags with Expo Updates context vars to make them searchable/filterable

[alwx]

📢 Type of change

• Bugfix
• New feature
• Enhancement
• Refactoring

📜 Description

A very small but potentially useful improvement — when running an OTA update via Expo Updates, we can set Sentry's release or add tags that allow correlating errors to specific OTA update deployments.
The existing expoContextIntegration already puts this in context, but context fields are not searchable in Sentry — only tags are.

📝 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.
• I updated the wizard if needed.
• All tests passing
• No breaking changes
