Update login lib hash that allows wpcom site address login for JetPack app

Now that Jetpack site filtering is removed as part of Jetpack App - Enable Features (#15946), this PR updates login lib hash for a fix that matches wpcom site address login in the Jetpack app with the WordPress app.

To test:

1. Install Jetpack app.
2. Click "Enter your exiting site address" on the Landing screen.
3. Enter a wpcom simple site address (note that the Jetpack app already allowed atomic site address login earlier as it has Jetpack installed, so make sure you specifically test a wpcom simple site).
4. Notice that the app directs to the email login screen.
5. Follow the log in steps.
6. Notice that the login is successful.

Merge Instructions

This issue was noticed during beta testing 19.3-rc-1 (p5T066-31e-p2#comment-11484), and so targets release/19.3 branch.

• Make sure that linked login lib is merged to trunk. I can take care of the merging tomorrow.
• Update login lib version inside build.gradle.
• Remove Not Ready for Merge label and merge the PR.

Regression Notes

1. Potential unintended areas of impact
   Minimal changes are included in the linked login lib PR that filters out wpcom sites from the connect site info handling for the Jetpack app. These sites are handled by the fallback method that redirects them to WordPress.com email login similar to the WordPress app.

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

3. What automated tests I added (or what prevented me from doing so)
   Login lib does not support unit testing for this flow.

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.

👋 @AliSoftware

I updated login lib version to trunk commit. I just realized I should have created a tag and updated that instead. Can you please confirm?

[AliSoftware]

Yes for code frozen branch we should indeed use a tag 🙇‍♂️
In this case bumping the patch version (3rd digit) is usually the way to go for a betafix that happened after the freeze.
