Differences from `urfave/cli/v2` to `v3`: `DefaultText`, `cli.StringSlice` and quotes

[enrichman]

While migrating from urfave/cli/v2 to v3 I have found few differences in the generated docs.

DefaultText

I have a cli.StringFlag with a DefaultText (default text of the flag for usage purposes):

&cli.StringFlag{
	Name:        "kubeconfig",
	Usage:       "kubeconfig path",
	Destination: &appCtx.Kubeconfig,
	DefaultText: "$HOME/.kube/config or $KUBECONFIG if set",
}

Is it expected?

cli.StringSlice

Moving from the cli.StringSlice to the []string is adding the empty slice as default:

// v2
**--agent-args**="": agents extra arguments

// v3
**--agent-args**="": agents extra arguments (default: [])

quotes

Quotes for the default strings are missing:

// v2
**--mode**="": k3k mode type (shared, virtual) (default: "shared")

// v3
**--mode**="": k3k mode type (shared, virtual) (default: shared)

@enrichman For cases 1 and 3 that shouldnt be happening. Can you raise an issue in urfave/cli ? For case 2 I have to look closer.

I did that for DefaultText now -> urfave/cli#2210

I wish I have an ability to test that this is fixed without leaving the web interface. 😀

just look at the test files, they should reflect that ...
