fix: FSC build CLIENT fix. (#757)

Note: 
Bypassing checks because this PR is fixing integration tests which work with a given branch. We tested it with this branch and then changed the actual code to use master which is why its failing here but it will work for master when merged

## Summary
- FSC needs CLIENT to run js sdk, which was missing in our integration-test yaml. I have made it fixed, once this PR Is merged, we should have proper status of FSC in our checks.

## Test plan
- I have tested in our last checks and works fine. for now i have pointed to master branch which will be used to take configuration for running CI.
