`ptree` crate is old and uses old outdated dependencies

[alamb]

Describe the bug

ptree was added as a dependency in #7192

However the most recent version of ptree is 2 years old https://crates.io/crates/ptree/versions

And it pulls in older versions of serde and various other dependencies.

To Reproduce

Look at datafusion-cli/Cargo.lock

Expected behavior

I would like to avoid all the old dependencies -- so either by updating ptree somehow or maybe simply by avoiding the dependency

Additional context

No response

@avantgardnerio any thoughts here?

I only included it as a dev-dependency for ease of reading/asserting tree balancing. Let me see if I can find another equivalent crate, or we can do more ugly asserts.

how's this:? https://crates.io/crates/termtree

I checked - it has no dependencies. I'll sub it in shortly...
