Remove code that set tracesSampleRate to 0.0 for Spring Boot if not set

[adinauer]

📜 Description

Remove some workaround code that was there to not require users to set a flag (that is no longer there).

💡 Motivation and Context

This caused sentryOptions.isTracingEnabled() to return true (as it should in this case) for a fresh setup without any performance options set causing Tracing without Performance code (#2788) not to be used.

💚 How did you test it?

Manually

Looks fine, but could it be considered a breaking/behavioural change?
If so, we should at least point it out better in the changelog
