Fix Anthropic integration when using tool calls

[kwnath]

Description

If you've initialized Sentry with Anthropic integration, streaming responses with tool calls fail.

The reason is quite simple, the API introduced a new data model for a ContentBlockDeltaEvent. This new refactor was made in 0.27.0 because json was needed to be streamed back (so arguments were returned as json for tool calls, I think this was the initial reason). This introduced a new data type InputJsonDelta that had it's contents in partial_json instead of what is currently supported text (reference).

And you'll find in the original integration we try to get the text if the type is a content_block_delta, this doesn't exist if you're doing any sort of tool calling with streaming. This doesn't fail however if you turn off streaming.

More info on reproduction steps here

Side notes

• Backwards compatibility is probably not that important but I'd rather be safe here.
• I've only updated this for ContentBlockDeltaEvent, there are likely other incompatible areas but this is the most breaking one. (I can add a few follow up PR's)

Hey @kwnath !

Thanks again for your contribution! I finally had some time to look at your PR. I took the liberty to change some stuff to bring it over the finish line. When all the tests have passed, this is ready to be merged!

@antonpirker Looks like the codecov/patch is stuck 😅
