Fix #3122 : Dark theme make colors of the images distorted

Explanation

Fix #3122 : Dark theme make the colors of the images distorted

Solution: Images change their color to white when Dark mode is turned on. That's why we force disabling dark mode for Image Views prevents android from force-inverting the colors in the images.

@BenHenning PTAL, Thanks!

Now I am wondering that how I will test this in release version, the solution you give without that also if I test app on my Physical device the output is without any bug as mentioned in screenshot. But now the major concern is how I will test this changes with release data or release app?

[Debug] Physical device output with and without changes is same

Also app is not building with forceDarkAllowed giving this error
Error - error: attribute forceDarkAllowed (aka org.oppia.android.app.databinding:forceDarkAllowed) not found
Solution - https://stackoverflow.com/questions/56163187/aapt-error-attribute-androidforcedarkallowed-not-found

Everyone saying to update compileSdkVersion but already on 31.

@MohitGupta121 can you check the build on Bazel to see if the attribute issue exists? Also, I think we need to check that this works on an earlier version of Android to make sure that the attributes won't cause an issue.

Once these are addressed, I can check this PR with production assets.

@BenHenning I getting same errors while building with Bazel, when using forceDarkAllowed=true
