Present twice in the menu system

When I was working on early Drupal 11 solution the admin toolbar module was not available for Drupal 11. What I was trying to do, was to display "Menu Migration" as a parent section within the Configuration area with the children "Export Types" and "Import Types" underneath. If I remember correctly, I couldn't easily achieve that within the Development section. So, I did something that's similar to the Devel generate module that has a second menu "Generate" under Configuration with the intention of skipping a click for the Import Types. Thoughts?

I think I prefer to just show it under /admin/config/development/menu-migration, on the same level as /admin/config/development/configuration, which is the most similar other menu entry, handling configuration export and import ...

I created an MR which does this. What do you think?

Here's my conflict:
1. I agree that there should be only one menu item within the Development section
2. I dislike the fact that there will be a longer path of clicks to get to the desired pages

Therefore at the moment I'll accept the changes, and see if there will be feedback on this in future versions. After all, there's the option of Shortcuts available to everybody. We'll see how it goes.
Thank you!

Adding a note that we might need to review README and Documentation for these changes in case it's needed.

Thanks for the flexibility and openness to try it out. As I see it:

1. I rarely use the UI for navigation, mostly if I need to check if an update like this works. Otherwise, I always use Admin Toolbar :)
2. The Configuration section is already quite crowded with 9 entries in my vanilla Drupal installation ... so keeping it in check is best, as I see it

I forgot to update the configure key (the one that generates the links in the Extend section and after installing a module with Drush) in menu_migration.info.yml, sorry about that. Maybe you can do it manually, instead of me creating a new issue?

From:
configure: entity.mm_export_type.collection

To:
configure: menu_migration.menu_migration

Valid points. I updated the key, thanks!

Perfect, thanks!
