Project dependencies may have API risk issues

[PyDeps]

Hi, In nbclient, inappropriate dependency versioning constraints can cause risks.

Below are the dependencies and version constraints that the project is using

jupyter_client>=6.1.5
nbformat>=5.0
nest_asyncio
traitlets>=5.2.2

The version constraint == will introduce the risk of dependency conflicts because the scope of dependencies is too strict.
The version constraint No Upper Bound and * will introduce the risk of the missing API Error because the latest version of the dependencies may remove some APIs.

After further analysis, in this project,
The version constraint of dependency jupyter_client can be changed to >=7.0.6,<=7.3.4.

The above modification suggestions can reduce the dependency conflicts as much as possible,
and introduce the latest version as much as possible without calling Error in the projects.

The invocation of the current project includes all the following methods.

The calling methods from the jupyter_client

jsonutil.json_clean

@developer
Could please help me check this issue?
May I pull a request to fix it?
Thank you very much.

I will second this, I encountered a breaking event loop bug from jupyter_client>=6.1.5 because it installed 8.0.0a, an alpha release. Downgrading to the latest stable version 7.4.7 fixed my issue.

The decision was made to not add upper bounds to dependencies.
