feat: Add logger to logger example

[mcmah309]

initializing the logger was missing from the logging example so nothing was ever logged.

Hmmm - are you sure the logger isn't working? dioxus::launch enables the dioxus-logger crate provided the "logger" feature is enabled (which it is by default).

Ah yes, you are correct. I had these small changes from a few weeks ago when I worked on #3775 and misremembered the reason I made them. I was starting work on somthing else in dioxus so I decided to commit them in this small PR. Still, might be a good idea to include explict logging setup in the logging example. If not, feel free to close.

Side: In addition to #3775 , I thought it would be a good idea to add programmatic filtering to the api e.g. Targets . Which would allow web support for filtering as well. And adding https://crates.io/crates/tracing-log as default might be worthwhile as well (crates like rfd use the log crate so nothing gets logged without it) . But I was waiting on feedback on that PR before doing anything.
