some repositories need $repos to be empty value but limit doesn't allow for that

[XANi]

Describe the Bug

    qownnotes:
        comment: QOwnNotes
        location: http://download.opensuse.org/repositories/home:/pbek:/QOwnNotes/Debian_11/
        release: /
        repos: ""

stopped working. This particular package repository doesn't need/use release/repos at all:

http://download.opensuse.org/repositories/home:/pbek:/QOwnNotes/Debian_11/
https://www.qownnotes.org/installation/debian.html

and similar problem for

https://pkg.origin.jenkins.io/debian/

APT has no problems with it

deb [arch=${ARCHITECTURE} signed-by=${SIGNED_BY}] http://download.opensuse.org/repositories/home:/pbek:/QOwnNotes/Debian_12/ /

and it worked in previous versions, but in 10.0.0/10.0/1 just gives me

Error: Evaluation Error: Error while evaluating a Resource Statement, Apt::Source[qownnotes]: parameter 'repos' expects a value of type String[1] or Array[String[1]], got String (file: /var/lib/dpp/repos/public/modules/core/manifests/init.pp, line: 34) 

passing string containing one space works as workaround

Same as #1132?

Kinda. I think it should still be required but allow empty value, because not having repos is pretty rare, so there is a bigger chance of "someone forgot to add repos" than "they did that on purpose because repos isn't needed"

Also got this bug for:

https://github.com/voxpupuli/puppet-proxysql/blob/master/manifests/repo.pp#L20

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement, Apt::Source[proxysql_repo]: parameter 'repos' expects a value of type String[1] or Array[String[1]], got String (file: /opt/puppetlabs/puppet/modules/proxysql/manifests/repo.pp, line: 24) on node foo
