What this PR does / why we need it?
Previously, we replaced istanbul-instrumenter-loader with
coverage-istanbul-loader to address critical vulnerabilities.
However, this change resulted in improper line positioning within the
debugger.
To resolve this issue, this commit reverts back to using
istanbul-instrumenter-loader.
Additionally, in the future, we plan to replace the Karma-based test
runner with vitest.
