[BUG]: Instrumentation tests fail to build

[BenHenning]

From a git bisect investigation, it seems this was introduced in 164f33b via #5098.

From that PR, it seems extremely likely the issue was introduced from this line: https://github.com/oppia/oppia-android/pull/5098/files#diff-b39b7c940cf9f44a11a5f82a5395e85f4f08cbf5117a9d8df38b267a3a64bf76R28. This makes sense since //testing would pull in Robolectric (which is the Maven target failing to be desugared) which has desugar issues (bazelbuild/bazel#13684 is a related issue I've seen before that's likely caused by the same root problem with our use of an old dexer).

Given how large #5098 is, I think I'm going to opt for a fix-forward since the regression is fully isolated to //testing.

@BenHenning, the line linked in you comment above doesn't actually load to the expected line when url is clicked. Could you link it on develop?

This does build on CI? could it be related to your OS?

[BenHenning]

@adhiamboperes we don't build instrumentation tests on CI which is why this was missed originally. While I'm only using Linux, it fails on both of my workstations that I tried setting it up on, and in CI when updated to include the builds (see #5335).
