When running process return all metadata, not just process_instance_key

[hoou]

Is your feature request related to a problem? Please describe.
We want to log and store the version of the created process instance when calling run_process. At the moment, it's not possible since the run_process function returns only process_instance_key: int. We had to hack it (patch it) in our codebase to get all relevant info from Zeebe API.

Describe the solution you'd like
It's not hard to implement, as Zeebe API already provides all the necessary info, documentation here, namely: process_instance_key, process_definition_key, version and bpmn_process_id. For some reason, the current implementation in pyzeebe currently takes only process_instance_key from the bigger response and passes it further.

I already have the solution prepared. Plz check it out and give me your feedback: my forked repo

Describe alternatives you've considered
I considered hitting Operate API every time after we create a process instance, but that is stupid, slow, inefficient, doesn't make sense, and Operate API can be down.

Additional context
I'm the first-time contributor here, so plz bear with me :D

Also, what I'm struggling with is the version of the package. According to the semver versioning, it should be a major version change (3->4) because of breaking change - I'm changing the response of existing functions. So either you're OK with that, and we will bump the major version, or I would have to implement a backward-compatible solution (probably new functions), which will bump a minor version (adding a new feature). Wdyt?
