`quarto_inspect()` should forward error message

[salim-b]

Currently, quarto_inspect() does not forward the error message when it fails:

Sys.setenv(NO_COLOR = "1")

# create new quarto book project
path_tmp <- tempdir()
path_tmp_proj <- file.path(path_tmp, "test")

quarto::quarto_create_project(name = "test",
                              type = "book",
                              dir = path_tmp,
                              no_prompt = TRUE)
#> WARN: No 'title' for project provided in `quarto create project`. Using 'test' as default.

#>   - Created intro.qmd
#>   - Created summary.qmd
#>   - Created references.qmd
#>   - Created cover.png
#>   - Created references.bib

# quarto inspect runs successfully
quarto::quarto_inspect(input = path_tmp_proj) |> is.list()
#> [1] TRUE

# rename intro chpt file to trigger error
file.rename(from = file.path(path_tmp_proj, "intro.qmd"),
            to = file.path(path_tmp_proj, "no_intro.qmd"))
#> [1] TRUE

# now quarto inspect fails – without forwarding the error
quarto::quarto_inspect(input = path_tmp_proj)
#> Error in `quarto::quarto_inspect()`:

The error message emitted by the underlying quarto inspect is the following in the above case:

$ quarto inspect /tmp/Rtmpin5zHs/test
ERROR: Book chapter 'intro.qmd' not found

ERROR: Book chapter 'intro.qmd' not found immediately indicates what's the problem, so we should really forward it.

Can you please explain why this is a cli issue?
