test_console_adapter: fix test failures caused by console gem update (#5360)

**Which issue(s) this PR fixes**: 
Fixes #

**What this PR does / why we need it**: 
The `console` gem changed its duration log format from ` 0.0s` to `
0.00s` in version 1.35.0 (socketry/console@14cf37d).

This caused assertion failures in `ConsoleAdapterTest` when running on
newer Ruby versions (3.3+).

This patch will fix following error
