Bug: 0.20.0 fails to compile under yarn2 pnp

[leaumar]

Renovate-bot attempted to upgrade type-fest to 0.20.0 during the night. The CI build fails with the following:

tsc -b
.yarn/cache/type-fest-npm-0.20.0-9c17c80bf4-420f4bc536.zip/node_modules/type-fest/ts41/camel-case.d.ts(1,30): error TS2307: Cannot find module './utilities' or its corresponding type declarations.
.yarn/cache/type-fest-npm-0.20.0-9c17c80bf4-420f4bc536.zip/node_modules/type-fest/ts41/delimiter-case.d.ts(1,51): error TS2307: Cannot find module './utilities' or its corresponding type declarations.

Typescript 4.1.2

{
    "compilerOptions": {
        "incremental": true,
        "module": "commonjs",
        "noUncheckedIndexedAccess": true,
        "strict": true,
        "target": "es2020"
    }
}

Can you try out https://github.com/sindresorhus/type-fest/releases/tag/v0.20.1 ?

@voxpelli Any idea why the tsc run didn't catch this?

Build passes with 0.20.1, thank you

[voxpelli]

@sindresorhus The tsc isn't run on the ts41 folder as then it would fail on all the older TS versions, but the tsd should have caught it as its run on all files 🤔

[sindresorhus]

@voxpelli Ah yeah, my bad. I disabled tsd because it was failing on the normal tests. tsd will soon support TS 4.1. So I think we can just leave it until then.
