Use glue's .literal argument

[jennybc]

Fixes #370

This is a rather quick / naive PR, but I just want to demo that the new .literal argument of glue allows #370 to be addressed.

These are results with dev glue and this PR:

Update: the new .literal argument now exists in glue 1.6.0, released on CRAN 2021-12-17.

#pak::pkg_install("tidyverse/glue")
library(glue)

cli_dl(
  c(
    "test_1" = "all good",
    "test_2" = "not #good (ok now!)",
    "test_3" = "no' good either (ok now!)",
    "test_4" = "no\" good also (ok now!)"
  )
)
#> test_1: all good
#> test_2: not #good (ok now!)

#> test_4: no" good also (ok now!)

Thanks! .literal is indeed great, and I did this in 64a389e with some other changes (and then mistakenly closed this PR with it).
