Imports in mockery generated files do not comply with goimports standard when package name does not match directoryname

[ArnoSen]

Description

At our company we use mockery extensively and it is a great tool. Thanks a lot for all the effort that you have put in!

When you import a package whose package name does not match the directory name, mockery generates go files that are changed after running 'goimports'. In our case, this makes our pipelines fail if I do not 'post process' generated files with 'goimports'

Reproducer

1. Install mockery 3.7.0 .
2. Create a new 'mockery' go project in an empty directory with 'go mod init mockery'
3. Create the below directories and files:
   ├── foo
   │   └── bar.go
   ├── .mockery
   └── pkg
   └── pkg.go

foo/bar.go:

package bar // NB: note that the package name is different from the directory name

type Bar struct{}

pkg/pkg.go:

package pkg

import (
        bar "mockery/foo"
)

type Getter interface {
        Get() *bar.Bar
}

.mockery:

packages:
  mockery/pkg:
    interfaces:
      Getter:
        config:
          filename: "pkg_mock_test.go"

4. Run 'mockery'
5. You should see a new file pkg/pkg_mock_test.go and get the first lines:

$ head pkg/pkg_mock_test.go
// Code generated by mockery; DO NOT EDIT.
// github.com/vektra/mockery
// template: testify

package pkg

import (
        "mockery/foo"

        mock "github.com/stretchr/testify/mock"

6. Run 'goimports' on the generated file:

$ goimports pkg/pkg_mock_test.go | head
// Code generated by mockery; DO NOT EDIT.
// github.com/vektra/mockery
// template: testify

package pkg

import (
        bar "mockery/foo"

        mock "github.com/stretchr/testify/mock"

7. Note that there is a change:
   Mockery generated "mockery/foo"
   Goimports changed that to bar "mockery/foo"

Expected behavior

I would expect after generation of the mocks with mockery, the format complies with 'goimports'.
In this specific example I would expect the import line to be bar "mockery/foo" instead of "mockery/foo"

8. If you think this could be improved/fixed, I would be happy to create a PR for it.

You can configure goimports however you want to change this: https://pkg.go.dev/github.com/vektra/mockery/v3/config#GoImports

You can also disable it entirely if you want. Mockery does run goimports, but we only FormatOnly: true by default because goimports is buggy and sometimes creates invalid code.
