Update create-toolpad-app to match engines

[bharatkashyap]

• From Cannot read properties of undefined (reading 'F_OK') #2092 (comment), we should have a node version check before running
• We should also add engines to the package.json file created by create-toolpad-app This is up to the user, as long as we don't generate code that is incompatible with certain node.js versions then the restrictions of @mui/toolpad-app and create-toolpad-app should do their jobs.
• Also a .gitignore on the root level with node_modules inside it so that this step does not have to be manually done when committing the project? @Janpot

I think we can leave this one up to the user, as long as our package has a correct engines field it should be fine.

Sure, we could initialize with https://github.com/github/gitignore/blob/main/Node.gitignore. Do we consider a folder empty if it only has a gitignore?

What range do the engines field? May I contribute to this issue?

[Janpot]

I meant it's up to the toolpad user to decide the engines range of their project, we don't need to choose it for them. I've updated the issue description.

OK I check the node version of the package is >=16.1
I will check the node version greater than or equal 16.1 before it runs.
and we initialize with that link
Please tell me if there is any error message.

May I ask what the meaning of the DX is?
what's the full name?
