fix: add missing peer dependencies

[merceyz]

What's the problem this PR addresses?

fork-ts-checker-webpack-plugin depends on some peer dependencies without declaring them as such, this makes it rely on hoisting to place the dependencies in an accessible location which is not guaranteed to happen.

How did you fix it?

Declare typescript and webpack as peer dependencies and vue-template-compiler and eslint as an optional peer dependency

@piotr-oles could you please look into this issue? I've stumbled upon the fact that ForkTsCheckerWebpackPlugin isn't listing it's peer dependencies correctly. This leads to some serious problems when incorrect version of webpack is getting resolved by package manager. Which in turn leads to typing errors (i.e. webpack ≠ webpack).

pnpm workaround

If you are using pnpm, you can temporarily fix this problem using the following pnpmfile.js:

module.exports = {
  hooks: { readPackage },
};

function readPackage($package, context) {
  if ($package.name === 'fork-ts-checker-webpack-plugin') {
    $package.peerDependencies.webpack = '^5.0.0';
  }
  return $package;
}

@piotr-oles What's status of this PR? The latest comment was that it would produce unwanted warnings, however this is not the case since all major package managers support peerDependenciesMeta and these peer dependencies would be marked as optional.

I would be happy to create a new PR that specifically targets alpha so we get the added benefit of releasing it in a major version in case it causes issues.

[piotr-oles]

I think we can merge this to the main branch if it's well supported :)

@piotr-oles Awesome! Looks like it just needs to be approved.
