Revert unintentional update to "name" field for jjsisson

"Name" field for @jjsisson somehow got updated to "Senior Site Reliability Engineer" after the initial merge, or perhaps a job didn't finish correctly initially.

Why is this change being made?

The commit history shows the file's "name" field was reverted after my original MR was merged. I do not know the precise reason why, but this MR fixes the revert so the teams page will show my name instead of my role for "name".
