fix: allow for init to pixi.toml when pyproject.toml is available.

[ruben-arts]

Adds a dialog for pyproject.toml use, and an option to overwrite the dialog with --format pixi

> pixi init --format pixi # forces to always use pixi.toml
# And:
> touch pyproject.toml
> pixi init

A 'pyproject.toml' file already exists.
Do you want to extend it with the [tool.pixi] configuration? [y/N]

Fixes #1615 #1207

Mm could we rename the flag to something like --force-pixi-toml or something like that? I think --pixi is a bit ambiguous.

This diagnostic only ever applies to dialoguer so I would just move it in the if branch.

I think because the other CLI flag is --pyproject, that --pixi was chosen.

I understand that, but pixi init --pixi just seems very ambiguous, does it not?

Indeed, maybe we could have something like --style=pixi-manifest --style=pyproject-toml as additions? Not sure. I think the force also sounds a bit forced haha

edit

or add --pyproject-toml and --pixi-manifest or something? Keep --pyproject to be backwards compatible I suppose.

[baszalmstra]

Any of those are better than --pixi. I think I like --style=pixi or --style=pyproject the best because it leaves the door open for other stuff.

[ruben-arts]

I guess, having autocompletion would be nice here. So --pixi-toml and --pyproject-toml seem most comfortable to me. If pixi would support more manifests styles we should indeed make it a option instead of a flag.

[baszalmstra]

Dont you also get autocompletion for the style option?

You would need to write a dynamic complete script for each shell and patch the completions scripts.

Edit: this does work for enums indeed.

[baszalmstra]

Not if style is just an enum right? At least thats the case for nushell conpletions I think.

@baszalmstra Updated this. Now it's --format pyproject and --format pixi, I deprecated the --pyproject to allow for CI to not break on update.
