Revert "Bump the "make request to service test app" retry timeout to 10 minutes [#62674726]"

This reverts commit 82ab000a93a7a9a856fb81f9cafb4003e6be01b7.

We discovered that even a 10 minute timeout won't work. Sendgrid is
actually experiencing a production issue now.
Marking sendgrid test as pending - they're having production issues

Since we marked it pending inside the it block, the build will fail as
soon as the test starts passing again.
