Protocol "s3" not supported or disabled in libcurl

[robbibt]

Describe the bug We are attempting to improve access to our Digital Earth Australia satellite data for R users, and rstac looks like a perfect option to replicate functionality we currently have via Python's pystac.client package.

I can successfully download STAC assets using the example code provided by rstac using the code below:

library(magrittr)
library(rstac)

stac("https://brazildatacube.dpi.inpe.br/stac/") %>%
  stac_search(collections = "CB4-16D-2",
              datetime = "2019-06-01/2019-08-01",
              limit=1) %>%
  stac_search() %>%
  get_request() %>%
  assets_download(asset_names = "thumbnail", output_dir = tempdir())

However, when attempting to download similar data from the Digital Earth Australia STAC endpoint (https://explorer.sandbox.dea.ga.gov.au/stac), I get the following Protocol "s3" not supported or disabled in libcurl error:

stac("https://explorer.sandbox.dea.ga.gov.au/stac") %>%
  stac_search(collections = "ga_s2am_ard_3",
              datetime = "2019-06-01/2019-08-01",
              limit=1) %>%
  stac_search() %>%
  get_request() %>%
  assets_download(asset_names = "nbart_red", output_dir = tempdir())

To Reproduce Run code example above.

Additional context We are able to successfully find and download data without issues in Python using the workflow documented here: https://knowledge.dea.ga.gov.au/guides/setup/gis/stac/
