upgrade to latest version of invokeai (3.7)

Thanks for this awesome work!

I might try and do this myself and contribute, but just wanted to add it here in case some effort towards this have already been made.

invoke-ai seems to have an upstream flake.nix of their own. Might be easier to use theirs, or just pull theirs as an input.

@jaduff did you read the flake? https://github.com/invoke-ai/InvokeAI/blob/main/flake.nix#L1-L6

[adrian-gierakowski]

That flake is quite old as well. There is no docs in the repo mentioning it so not sure if it still works. For one, building the frontend now requires pnpm while the devshell in the flake only contains yarn

@MatthewCroughan what would it taken to get this done? Happy to help, but might need some guidance since I'm not supper familiar with packaging python.
