chore: hoist the trace's conditional segment out of the template [ENG-2472]

SonarCloud typescript:S4624 on the previous commit — a nested template
literal. Hoisting the removed-keys segment into its own const also makes this
match the other three SDKs, which all build that fragment as a local
(`let removed` / `val removed` / `final removed`) rather than inline. Same
output, and the trace tests are unchanged and still green.
