cannot run gallery apps according to `README`

The `README` for `teal.gallery` says:

> Running the restore_and_run("APP_NAME") will run the APP_NAME by restoring the packages using [renv](https://rstudio.github.io/renv/)
`restore_and_run("basic-teal")`

This does not work. First, the link to `sourceme.R` is 404, the file has been moved to `teal.galley/_internal/utils`.
Second, this happens:
```
> source("./_internal/utils/sourceme.R")
> restore_and_run("basic-teal")

# Bootstrapping renv 1.0.3 ---------------------------------------------------

I can run the app with
```
(apps <- list.files(pattern = "app\\.R", recursive = TRUE))
shiny::shinyAppFile(apps[1], options = list("launch.browser" = TRUE))
```
to use my won environment but that's not the point, is it?
