use_lifecycle() raises an error, uses_roxygen_md() is confused by roclets

[nkehrein]

My package's DESCRIPTION file contains the following lines:

RoxygenNote: 7.3.2
Roxygen: list(markdown = TRUE, roclets = c("collate", "namespace", "rd",
    "roxyglobals::global_roclet"))

When I try to execute the following statement to add support for the lifecycle package:
> usethis::use_lifecycle()
Then the following error appears:

Error in if (!uses_roxygen_md()) { : 
  missing value where TRUE/FALSE needed

I have tested this with usethis version 3.0.0 and R 4.3.0.

As far as I can tell, the issue is because of this check, which doesn't seem to account for the existence of roclets in the config object.

I came here to open the same issue. 😸

Could the current condition be made more flexible, maybe only checking the string starts with list(markdown = TRUE? roxygen2 evaluates the field.

Thank you @jennybc 🙏
