fix(sagemaker): Reduce number of reconnect retries (#7827)

## Problem
When a connection to a remote space is severed, the extension will
attempt to reconnect up to 60 times. Each reconnect attempt opens the
Space Details page in a new browser tab. Opening up to 60 new tabs is a
poor user experience.

## Solution
We change the maximum number of retries to 8.
