Bump applicationinsights-web package to 2.5.7 (#10)

Update the application insights package to be in sync with applicationinsights-react-js SDK version. As reported in application insights GitHub issue microsoft/ApplicationInsights-JS#1346, there are 2 SDKs of applicationinsights-web gets downloaded during deployment with different version and in turn causing conflicts due to version mismatch.

note: the fix will temporarily solve the build failure issue. It will be permanently fixed by removing the conflict dependency of applicationinsights-web from dependent components.
