a4ab1101 - test: replcompletions: Replace timedwait by proper condvar (#58643)

test: replcompletions: Replace timedwait by proper condvar (#58643) Replace fragile timing-based synchronization with proper condition variable signaling to ensure PATH cache updates complete before testing completions. This eliminates test flakiness on systems where the cache update takes longer than 5s. The test failure was seen in CI: https://buildkite.com/julialang/julia-master/builds/48273
