#2765 strikes again

We need to do the same with APM / Observability as far as the new logo goes. Replace APM and deprecate, then make a new Observability one.

Sorry, I missed that in my instructions. Your code looks correct though.

cc @elastic/observability-design and @MichaelMarcialis for visibility that these changes are coming.

Updated view with logoObservability instead of logoAPM

Thanks! Double checked the deprecated logos still work and spit out the new icons. Please add a deprecation note to this CL. You can see an example in the 14.0.0 release.

@snide I would have thought we'd deprecate Logging, Metrics, and Uptime too because we're adding a single Observability solution logo?
