What's the problem this PR addresses?

es-toolkit is a modern lodash alternative that claims to be much faster and lighter, potentially improving Yarn overall performance: https://es-toolkit.slash.page/intro.html

How did you fix it?

The lazy way, frankly: using es-toolkit/compat to provide practically drop-in lodash replacement with minimal effort.

Some of our dependencies are using lodash so this would increase the install size and maybe the bundle size.

Valid point, but it seems like not too many dependencies are in fact using lodash. It should be relatively easy to clean this whole tree up. In the meantime, this draft PR is in itself ready to go I believe. :)

Well, this PR DOES make Yarn smaller by a bit:

Before: 2.63 MiB

After: 2.61 MiB

I believe that's because while other dependencies like ink (not anymore) are indeed using lodash, they, just like Yarn, are importing modules selectively from it, leading to better tree shaking than one could initially assume.

1% improvement is not much but it certainly adds up 🤷

I also see a potential of shaving off further 2 KB, but I'd rather do it in small stages.

Because I patched it to do that, in the future we could change that patch to use es-toolkit instead.

Please add an entry for lodash and @types/lodash here:

forbidDependency(ctx, `inquirer`, `Don't depend on inquirer - we use enquirer instead`);

I couldn't forbid @types/lodash because it appears to be deeply rooted inside pkg-tests-specs, but lodash alone was fine :)

Update: the latest version of ink, our dependency, also switched from lodash to es-toolkit, making this PR more welcome than before, IMO. I'll work in getting my work rebased.
