Fix typings with esm

[stuikomma]

Hi, thanks for the lib! I am currently using it in my third project and got some type errors. This error appears when "moduleResolution" is set to "bundler" in tsconfig.json.

TS7016: Could not find a declaration file for module 'react-use-wizard'.
'/path/to/my/project/node_modules/react-use-wizard/dist/react-use-wizard.esm.js' implicitly has an 'any' type.

There are types at '/path/to/my/project/node_modules/react-use-wizard/dist/index.d.ts', but this result could not be resolved when respecting package.json "exports". 
The 'react-use-wizard' library may need to update its package.json or typings.

In my local test, this change fixed it.

Thanks for this PR, I really appreciate it

@devrnt Would you mind overriding the failing job? Or fixing it? I am not familiar with you CI setup. Otherwise, I'll just wait for #167 which should also fix it.

Can you sync your branch? Pipeline issue should be resolved
