Bump metadata.version from toJSON functions to 4.6.

[repalash]

Fixed: #25989

Description

Update the version number in toJSON functions to 4.6, to make it possible to determine old and new files, after changes in Color Management and how colors are serialized.

It seems the JOSN files for the unit tests need an update from 4.5 to 4.6 as well.

Thanks for fixing

@repalash This is just a minor suggestion but I would recommend for future PRs that you fork from mrdoob/three.js and not from another fork of three.js (in your case takahirox/three.js). Besides, the PR should also based on latest dev and not on an outdated branch.

Hey yes, I have been trying to do that, but I made this fork several years ago, and GitHub doesn't allow to have multiple forks from the same base repo. One way to do that is to delete the repo and fork again, but I have some branches and npm packages which will get deleted.
Do you have an idea if there's some way to make another fork? or any other suggestion?
Thanks

Um, using a different user would be a pragmatic solution. But I can understand if such contributions should be done under your normal account.
