Plugins added before LogPlugin don't have a plugin build tracing span

## What you did

Recently we added tracing spans for the plugin lifecycle methods. When running `cargo run --example many_foxes -F trace_tracy`, the plugins that are added before and including `LogPlugin::build` are not logged. This is just the `PanicHandlerPlugin` and the `LogPlugin` in `DefaultPlugins`.

I don't think this is easily fixable, but thought it should be noted somewhere.

Run `cargo run --example many_foxes -F trace_tracy` and inspect the plugin lifecycle tracing around `DefaultPlugins`, especially `PanicHandlerPlugin` and `LogPlugin`. Determine whether spans can cover plugins added before `LogPlugin::build`; done means those plugins are represented in the tracing output, or the limitation is documented if it cannot be fixed.
