Updates Ink package

[ViMaSter]

Summary

Inkle recently changed their package name and released a few updates. This PR changes the package to the new name and updates it from 1.1.1 to 1.2.1.

GitHub Actions Runs are flaky at the moment and some run failures seem to stem from the compileTimeout being ignored in batchMode:

1. Open https://github.com/Studio-Lovelies/GG-JointJustice-Unity/actions/runs/15085544932/job/42409223588?pr=513#step:9:1877
2. Select the cog icon at the top right and enable Show timestamps
   
3. Notice the timeout at Sat, 17 May 2025 14:51:08 GMT, while the step was started at Sat, 17 May 2025 14:48:17 GMT (less than 3 minutes)

Before I open a bug report on their package, I want to see if updating to the latest version resolves it.

Testing instructions

No gameplay changes; tests should succeed and the game can be completed as before.
