This PR updates androidDesugarVersion to 1.1.8.

FYI:

• Release Notes: N/A
• Documentation
• Google Maven Repository

Since 1.1.5 is outdated, with the latest v1 release (1.2.2) requiring an update to AGP 7.3.0 and above (see docs), while the latest v2 release (2.0.2) requiring an update to AGP 7.4.0 and above (see docs), the only possible update at this point is the 1.1.8.

PS: @ravishanker I added you as the main reviewer, randomly, since I just wanted someone from the WordPress team to be aware of and sign-off on that change for WPAndroid. I also added the @wordpress-mobile/apps-infrastructure team, but this in done only for monitoring purposes, as such, I am not expecting any active review from that team. Thus, feel free to merge this PR if you deem so.

To test:

• See the dependency tree diff result and verify correctness.
• Smoke test both, the WordPress and Jetpack apps, and see if they both work as expected.
• In addition to the above smoke test, you can focus on testing push notifications and/or blogging reminders since this was why this library was introduced to this project in the first place (see here and here).

Regression Notes

1. Potential unintended areas of impact

   • Not that I can think of, maybe push notifications and/or blogging reminders misbehaviour somehow, but I doubt it.

2. What I did to test those areas of impact (or what existing automated tests I relied on)

   • See To test section above.

3. What automated tests I added (or what prevented me from doing so)

   • N/A

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
