Subject: [PATCH] feat: allow multiple --author flags in poetry init

Change the --author option to accept multiple=True so users can pass
multiple --author flags (e.g. --author "Alice <a@x.com>" --author "Bob <b@x.com>").
Update the author processing logic in _init_pyproject to build the authors
list directly from all provided --author values, falling back to the
existing interactive/vcs-config behaviour when no flag is given.

Fixes #8864
