This is expected behavior since Fx 78 and logged in Tech plan Telemetry section https://docs.google.com/document/d/1EZHx1-qnXyCDWiH7GqgBvis8iEmqXtKgCwITZg9iY1E/edit#heading=h.h2fxax9w7ve

When about:welcome loads, we send impression pings for
a) Welcome UI is loading with message id MULTI-STAGE-WELCOME-IMPORTABLE-THEME
b) Impression respective to screen e.g. MULTI-STAGE-WELCOME-IMPORTABLE-THEME_AW_GET_STARTED
c) Pre-imported sites Impression ping MULTI-STAGE-WELCOME-IMPORTABLE-THEME_SITES

With simplified card experience with message_id ABOUT_WELCOME going away in Fx80, we can refactor and remove 'MULTI-STAGE-WELCOME-IMPORTABLE-THEME' impression ping as it will be redundant and same as 'MULTI-STAGE-WELCOME-IMPORTABLE-THEME_AW_GET_STARTED' for multistage
