Fixes #27103: Update front-end dependencies
https://issues.rudder.io/issues/27103
We now need to include ESM modules as the newer JS libraries, here jsondiffpatch are switching paradigm, or we could not upgrade (this is also the case for chartjs, but hopefully it still ships UMD dists). So there is some change in the gulpfile, we need to include the modules tree : there are javascripts imports and a single javascript entrypoint file is no longer sufficient to embark a library.
For bootstrap, the dependency upgrade is not breaking, there are simply some warnings that can be ignored from gulp, as discussed here, and it requires pinning the version of sass. Also the gulp-sass plugin API exposes a synchronous version which is reported to be more efficient.
There is some dependency vulnerability which needs to be fixed with an override because the package has not an up-to-date npm release but only a fix in the github source without any release (we should watch for upcoming versions of this package)
