feat: add webpack5 builder

[DevBlocky]

Adds a builder for webpack5 (webpack is stuck on webpack v4)

With this, people can finally build with webpack v5 only configurations, like what is required by Vue3. I'm unfamiliar with the node version in FiveM, so I don't know if you can install multiple versions of the same resource so I decided to split it into its own resource with the similar code.

You use webpack5_config instead of webpack_config to designate the different webpack version.
