Rollup merge of rust-lang#82938 - oli-obk:tracing_tree_bump, r=Mark-Simulacrum

Bump tracing-tree dependency

This bump fixes two small rendering things that were annoying me:

* The first level didn't have an opening line
* When wraparound happens, there was no warning, the levels just disappeared. Now there is a line that shows that wraparound is happening

See https://github.com/davidbarsky/tracing-tree/pull/31/files for how the look changes
