chore(sdk): adding auto retry to the sdk gh workflow (#3770)

From the few runs I looked into, it seems like the reason for failure is either a network error installing wing (is it blocked by NPM in any way?) or occasional fails in the tests themselves...
I added a retry option to make them more stable:
