[Bug]: Adding multiple external storages with the same protocol is buggy [UI refinement]

[Lenezir]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

When you go to External Storage and you want to create more than one folder with the same protocol (SMB/CIFS for example), the new blank line awaiting new data below already displays the potocol you used previously. Consequently, you won't be able to use that line.

If you unroll the list and click on the same protocol, nothing happens. You will have to choose another one to be able, with the next blank line, to select the desired protocol. Therefore, to create 10 effective SMB folders, you will have to create 10 unused lines. Fortunately, those lines can be deleted afterward.

Steps to reproduce

1. Go to External Storage
2. Create one share with a specific protocol
3. Try to create a second share with the same protocol

Expected behavior

I expect a reset of the protocol field when a new blank line appears.
