[engsys] pin dev dependency chai version to 4.3.10

Recent upgrade of `chai` from `4.3.10` to `4.4` broke our integration tests
which use `esm` to transform *.js test files.  The new version contains `??`
syntax that is not supported by `esm`.

This PR pins `chai` version to `4.3.10`. Issue Azure#28185 is created to track
follow-up work.
