Disable docker-in-docker for SAST
In support of Use non-DinD mode by default for Security Products, we want to DogFood DinD-less SAST.
We also recently made a fix to the nodejs-scan analyzer that has increased the total runtime of the SAST job, which causes it to be the bottleneck for some pipelines. We are working to Speed up SAST analyzer nodejs-scan, but in the mean time, this will also have the benefit of parallelizing the SAST analyzers we run, which should fix the problem of SAST being a bottleneck for pipeline runs.
