ts-essentials is listed as a devDependency

[freben]

However, dist/index.d.ts does import { MarkOptional } from 'ts-essentials';, which leads to

node_modules/rollup-plugin-esbuild/dist/index.d.ts:3:30 - error TS2307: Cannot find module 'ts-essentials' or its corresponding type declarations.

3 import { MarkOptional } from 'ts-essentials';
                               ~~~~~~~~~~~~~~~

because

declare type Options = {
    /* ... */
    optimizeDeps?: MarkOptional<OptimizeDepsOptions, 'cwd' | 'sourceMap'>;

Since this is a type dependency I prefer bundling it using tsup over adding it as a dependency , fixed in 4.9.1, anyways thanks for the contribution!
