Generate eslint flat config for new workspace

[robertIsaac]

Nx should generate new workspaces with the new flat configuration for eslint
And it's even better to use eslint 9 with typescript-eslint@rc-v8

@robertIsaac I generated a new project over the weekend with nx 19.8 and got a flat config using eslint 9 -- should be what you were asking for?

[robertIsaac]

yes this is done now
