Problem/Motivation
Drupal 10.0.x is currently still using Yarn 1 ("Yarn Classic"). Per https://github.com/yarnpkg/yarn#contributing-to-yarn:
The 1.x codebase is fairly old and will only accept security fixes. For new features or bugfixes, please see our new repository and its contribution guide.
That's been the case since Feb. 2020. I can't find any information about when security fixes for Yarn 1 will cease or how much notice the project will give prior to then.
Proposed resolution
Update to Yarn 4 by following the migration steps from https://yarnpkg.com/getting-started/migration.
We need yarn 4 to be released first, see: https://github.com/yarnpkg/berry/issues/3591
Remaining tasks
- The merge request for this issue has a merge error; resolve that.
- Review the MR.
- This MR removes the farbtastic library per #24. Find out why Color module tests still pass despite that.
- If the farbtastic library can't be removed without removing Color module, then we might need to postpone this on #3270899: Remove Color module from core.
