kratos cli gives wrong import path when creating app with --nomod parameter

[qzwxsaedc]

What happened:

1. create a go.mod with go mod init proj
2. create an app named "demo" with command kratos new demo --nomod
3. open a file whose import path needs to be replaced with a local file, such as internal/server/http.go
4. you can see that the import path does not conform to import path rules of golang. like this:

What you expected to happen:

import path should be github.com/CyanPigeon/toktik/demo/api/demo/v1 and github.com/CyanPigeon/toktik/demo/internal/biz in the example previous.

How to reproduce it (as minimally and precisely as possible):

1. create a go.mod by go mod init proj
2. create an app named "demo" with command kratos new demo --nomod
3. open a file whose import path needs to be replaced with a local file, such as internal/server/http.go

Anything else we need to know?:

kratos/cmd/kratos/internal/project/project.go

Lines 94 to 95 in 072b2ee

	p.Path = filepath.Join(strings.TrimPrefix(workingDir, projectRoot+"/"), p.Name)
	done <- p.Add(ctx, workingDir, repoURL, branch, mod)

Project.Path was set to an absolute path before Project.Add() is called.

kratos/cmd/kratos/internal/project/add.go

Line 43 in 072b2ee

if err := repo.CopyToV2(ctx, to, filepath.Join(mod, p.Path), repoAddIgnores, []string{filepath.Join(p.Path, "api"), "api"}); err != nil {

Here the absolute path is incorrectly concatenated with the module name via filepath.Join(), resulting in this error.

Environment:

• Kratos version (use kratos -v): kratos version v2.6.3
• Go version (use go version): go version go1.20.6 windows/amd64
• OS (e.g: cat /etc/os-release): Windows 11 22621.1992
