Option to limit the number of yes votes to the number of persons to be elected

Is your feature request related to a problem? Please describe.
In our organisation, we use the voting procedure with the options Yes / No / Abstain, whereby a maximum of as many Yes votes are awarded as there are people to be elected. To my knowledge, this as also a common system in other organisations. However, in OpenSlides there is no way to limit the number of Yes votes in an election with the Yes / No or Yes / No / Abstain options. We therefore always have to manually check all digitally submitted ballot papers to ensure that the maximum number of votes in favour is the same as the number of people to be elected.

Describe the solution you'd like
Add a selection field for elections with the options Yes / No or Yes / No / Abstain to limit the number of Yes votes to the number of persons to be elected.

Describe alternatives you've considered
Add (as with "yes only" and "no only" elections) an option to set the minimum and maximum number of yes votes.

Additional context

The issue mentions elections with Yes / No and Yes / No / Abstain options but names no files or tests. Start by locating the election configuration UI and its vote-limit validation, then define the selection field and verify that the Yes-vote limit matches the number of persons to be elected.
