No checklist directory error handling

[wes-a2ai]

A bug was found when attempting to clone a configuration information repository which did not contain a "checklist" directory due to an fs::dir_ls() call without checking if the directory exists before hand. Warning/communication if the checklist directory doesn't exist or is empty exists elsewhere in the code, so adding a verification step before listing the content within the directory helps to invoke that warning.

Additionally, creating a flag to force a new download of the configuration information repository within the download_ghqc_information function

Checklists dir dne locally:

sitrep

setup

Checklists dir dne remotely (cloning in for first time)

sitrep

setup

Here I:

• changed my renviron manually to a info repo that dne exist locally
• ran setup_ghqc

sitrep worked because it checked if the repo was local first, I think, but setup doesn't

problem was parsing env var without "" in Renviron: fixed!
