POTEL 64 - sentry-opentelemetry-agentless module

[adinauer]

📜 Description

Add sentry-opentelemetry-agentless module that customers can add as a single dependency to use our OpenTelemetry offering instead of having to add multiple dependencies and manage versions.

💡 Motivation and Context

Closes #3913

💚 How did you test it?

📝 Checklist

• I added tests to verify the 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.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

• Consider agentless-spring-boot that pulls in opentelemetry-spring-boot-starter with the required version
• Consider creating a BOM, that also drags in the OTel BOM to manage Sentry + OTel versions
• Update README
