Fix typos and add new flag to `create` command

[nickdotht]

Hey there :)

Thanks to your succinct video and article, I have a clear understanding of the vision for this project and I already love where it's going!

I'm starting off with super easy contributions :) Here are the changes introduced:

• Minor typo fixes and wording improvements In both code and comments
• New flag for the create command: --help. It can potentially become a default flag for all commands
• Introduce a .editorconfig file for people who have it supported in their editor

You call the new flag like so npx ts-node src/index.ts create --help

Current output:

Usage: doulevo create [options] <project-dir>

Creates a new Doulevo project at <project-dir>

Options:
    --force                  Deletes project directory if it already exists.
    --local-plugin           When set, Doulevo will create the project using the 'local' plugin from the specified location.
    --plugin-url             When set, Doulevo will create the project using the 'remote' plugin from the specified location.
    --project-type           When set, Doulevo will create the project using the default plugin for the specified project type.
    --debug                  Logs command executions in the terminal.
    --help                   Prints usage for this command.

Let me know if that's something you care to add and feel free to update anything if it's not correct.
