Add module configuration schema file

Added initial module schema file in merge request MR!4 above at #2.

The config type path used for the routes fields, is inspired from Drupal core system.schema.yml for the 403 and 404 pages path fields, defined on the basic site settings form, see:
https://git.drupalcode.org/project/drupal/-/blob/11.x/core/modules/syste...
without any specific validation constraints or rules.

See the result with config_inspector:

Any reviews and feedback would be greatly appreciated.
Thanks in advance!

Thanks a lot Matthew (@drupalmatts) for getting the changes merged above at #4, it's greatly appreciated!

Thanks also for creating the login_switch-3.x-dev → development release.

However, I'm not completely clear about the version naming of the branches:
The 3.x branch looks pretty outdated, going back to 2022, see:
https://git.drupalcode.org/project/login_switch/-/commits/3.x?ref_type=h...

and you've merged the changes above in the 8.x-dev branch:
https://git.drupalcode.org/project/login_switch/-/commits/8.x-dev?ref_ty...

which seems to be the current development branch.

What's the plan with the different branches?
Could we maybe remerge 8.x-dev into 3.x and move developments into 3.x?

This would simplify the understanding of module's code base and be more consistent with the stable version names, for example 3.0.3:
https://www.drupal.org/project/login_switch/releases/3.0.3 →

For the time being, I'll try creating MRs for the 8.x-dev branch.

Otherwise, not sure if you had anything else in mind with this issue but perhaps you could credit both of us and mark it fixed for now?
So we could move to fixing other tickets.

In any case, thanks again for your great help keeping the module maintained.
Cheers!
