[BUG]

[campbead]

Describe the bug
add_dockerfile_with_renv_shinyproxy() fails when working directory is not same as the golem project directory, even when supplying source_folder.

To Reproduce

1. create a new golem project golem.dummy in folder DUMMY_FOLDER
2. setwd("~")
3. run golem::add_dockerfile_with_renv_shinyproxy(source_folder = DUMMY_FOLDER)

Expected behavior
Expect to produce temporary deploy folder and files when using the source_folder flag. This works when the working directory is the same as DUMMY_FOLDER and running:
golem::add_dockerfile_with_renv_shinyproxy(source_folder = DUMMY_FOLDER)

hi,

what was your getwd() when you tried this ?

A new golem named pouet was created at pouet .
To continue working on your app, start editing the 01_start.R file.

colinfay@Colins-MBP /tmp % cd ~

You set `document = TRUE` and you did not pass your own renv.lock file,
as a consequence {golem} will use `attachment::att_amend_desc()` to update your 
DESCRIPTION file before creating the renv.lock file

you can set `document = FALSE` to use your actual DESCRIPTION file,
or pass you own renv.lock to use, using the `lockfile` parameter

In any case be sure to have no Error or Warning at `devtools::check()`
