[1.1.0] new version requires lib to include es2020 or later

[AviVahl]

@sindresorhus I believe this was an unintended breaking change.
after upgrading to type-fest@1.1.0, I started getting the following type errors:

$ tsc --build
node_modules/type-fest/source/typed-array.d.ts:14:4 - error TS2583: Cannot find name 'BigInt64Array'. Do you need to change your target library? Try changing the `lib` compiler option to 'es2020' or later.

14  | BigInt64Array
      ~~~~~~~~~~~~~

node_modules/type-fest/source/typed-array.d.ts:15:4 - error TS2583: Cannot find name 'BigUint64Array'. Do you need to change your target library? Try changing the `lib` compiler option to 'es2020' or later.

15  | BigUint64Array;
      ~~~~~~~~~~~~~~


Found 2 errors.

I can see that typed-array.d.ts is nothing new, so my guess is that the index somehow started referencing it, where it didn't before.

A workaround is to change my lib to "es2020", or more specifically add "es2020.bigint".
