"{}" as span names

[nekto0n]

Hi!
Noticed strangely named spans, which are literally {}. Examples include:

zbus/zbus/src/connection/mod.rs

Line 683 in 759a717

.instrument(info_span!("{}", lost_task_name)),

zbus/zbus/src/connection/mod.rs

Line 727 in 759a717

.instrument(info_span!("{}", task_name)),

zbus/zbus/src/proxy/mod.rs

Line 312 in 759a717

.instrument(info_span!("{}", task_name));

Looking at the history it looks like the intention was to assign a literal string to a variable to be able to reuse for other purposes.

If I am reading this correctly, then the proper solution would look like:

.instrument(info_span!(name: task_name))

Actually, the intention was just to assign a name/string to the task so traces include the context.

If I am reading this correctly, then the proper solution would look like:

.instrument(info_span!(name: task_name))

hmm.. can it just be:

.instrument(info_span!(task_name))

In either case, a PR would be most welcome.
