Consider making `Version.name` a property that references `Version.metadata["name"]`

We currently do some special processing of the "name" property of a Version that it seems like shouldn't need to be done. This would require changes across the codebase, so some discussion and clarification should come first.

See original discussion at https://github.com/dandi/dandi-archive/pull/1886#discussion_r1526372560

Start with the original discussion linked from the issue, in pull request #1886, to understand the proposed relationship between Version.name and Version.metadata["name"]. Then locate the Version implementation and all existing special handling of name across the codebase; the work is done only after the behavior and scope are clarified and agreed.
