Address issues related to testing with shinytest2 the examples

[llrs-roche]

Pull Request

Attempts to fix https://github.com/insightsengineering/coredev-tasks/issues/536 on this package.

1. system.file don't raise an error (but I need to check if it is empty or it reports useful info).
2. When there is an error on a shiny session the test of the example fails.
3. Stop using load_all inside test-examples.
4. Checks all examples due to upstream issues being fixed since last year.

For testing 2 create a new file and add a new file and document to add this example:

#' Example failing
#' @export
#' @examples
#' app <- init(
#' data = teal_data(
#'   new_iris = transform(iris, id = seq_len(nrow(iris))),
#'   new_mtcars = transform(mtcars, id = seq_len(nrow(mtcars)))
#' ),
#' modules = modules(
#'   module(
#'     "Iris Sepal.Length histogram",
#'     server = function(input, output, session, data) {
#'       stop("yada") # 🔍 this will fail the app
#'     },
#'     ui = function(id, ...) {
#'       ns <- NS(id)
#'       plotOutput(ns("hist"))
#'     },
#'     datanames = "new_iris"
#'   )
#' )
#' )
#' if (interactive()) {
#'   shinyApp(app$ui, app$server)
#' }
module_error <- function() {}

Then for all check with R CMD check or devtools::test(filter = "examples") from plain R session.
