[chore] Enable goleak for tests failing on opencensus-go (#9210)

**Description:**
As described
[here](#9165 (comment))
and
[here](#9165 (comment)),
there are quite a few packages that directly or indirectly import the
[OpenCensus-go stats
package](https://pkg.go.dev/go.opencensus.io/stats). Within the
[stats/view
package](https://pkg.go.dev/go.opencensus.io@v0.24.0/stats/view) there's
an init() function that starts goroutines that aren't cleaned up. This
causes goleak to fail.

Since the failure is caused by OpenCensus always indirectly (from what I
can tell), and OpenCensus is now read-only, I believe it's fair to
ignore leaks caused by this dependency and specific leaking situation.

**Link to tracking Issue:** <Issue number if applicable>
#9165

**Testing:**
All added tests are passing
