save_project MCP tool only supports a single team

Hello,
The save_project tool currently exposes a team field as a single string, which means it's only possible to assign one team when creating or updating a project via the MCP.
However, Linear's data model supports multiple teams per project.
Suggested fix: Update the team field in save_project to accept an array of teams, so multiple teams can be assigned through the MCP.
Thank you!
