Profiler data stream has invalid signature" errors are thrown when loading a .highlights file in the Profiler

Steps to reproduce:

1. Create a new URP project
2. Open Profiler (Window > Analysis > Profiler)
3. Change target selection from "Play mode" to "Edit Mode"
4. Click record button and record few frames
5. Click on the "Save current profiling information...” button
6. Click on the "Load binary profiling information from a file"
7. Select the .highlights file and open
8. Observe the Console

Actual results: "Profiler data stream has invalid signature. Was this Profiler data captured in a newer Unity version?" "Deserializer encountered error for /Users/.../....highlights" errors 

Expected results: The file loads gracefully without throwing exceptions, or the .highlights file extension is filtered out and restricted from being selectable
