update coroutines to 1.6.1, use CopyableThreadContextElement

[lbloder]

📜 Description

Use CopyableThreadContextElement as superclass for SentryContext.

💡 Motivation and Context

Fixes #2687.
Allows for correct progagation of the SentryContext to child-coroutines.
Context propagation now behaves as described in the docs here: https://docs.sentry.io/platforms/java/guides/spring/enriching-events/scopes/#usage

💚 How did you test it?
