`--adopt` is still recommended in the CLI docs

[DavisVaughan]

gh-stack/cmd/root.go

Lines 25 to 26 in 514f5ab

	# Or turn an existing set of branches into a stack
	$ gh stack init --adopt branch1 branch2 branch3

but using it results in a deprecation warning

gh-stack/cmd/init.go

Lines 119 to 124 in 514f5ab

	// --adopt is deprecated; print a notice and continue normally.
	if opts.adopt {
	cfg.Warningf("The --adopt flag is deprecated. Existing branches are now adopted automatically.")
	cfg.Printf("You can simply run: %s",
	cfg.ColorCyan("gh stack init <branch1> <branch2> ..."))
	}

looks like you can literally just remove the --adopt flag from the CLI docs and it would work the same
