feat: make globby includes dot files (#5537)

https://cli.vuejs.org/dev-guide/plugin-dev.html#filename-edge-cases

Although in this passage, it is suggested that we should change ".env" to "_env" to solve the problem of uploading npm packages. But there will also be such a demand, the files in `generator/template` are dynamically pulled from the git repository at runtime, and there may be `.env` files in the repository, so this pr can solve the problem here
