when testing earlier, 0.1.0 was used for a failed pypi upload. I'm
assuming this is why `This filename has already been used, use a
different version` is occuring
1. The Arcade Worker doesn't like it when the package name is different
than the directory name. This PR renames the directory from
`arcade_notion` to `arcade_notion_toolkit`
2. `Notion` is not a well-known provider name in `arcade-ai==1.0.5`,
I've updated the dep to represent this.
