feat(turborepo): web ui (#8895)
### Description
Implements a very very alpha version of a web UI. Uses a GraphQL query
to get the current run and tasks.
### Testing Instructions
Would love some ideas here on tests.
To try out manually, go to #35066 in the other repo and run
`turbo-studio`, then execute a turbo command with the `ui` flag set to
`web`
