Improve hy_list_available_hySpc_packages() (part 2)

[GegznaV]

Code in this PR unifies the GH API output for different machines.

Related to #3 and closes cbeleites/hyperSpec#328.

---

@bryanhanson and @cbeleites, could you test this new version of function on your machines and inform us if it works for you.

Otherwise, I'll need the output file of:

gh_api_response <- readLines(
  "https://api.github.com/orgs/r-hyperspec/repos?per_page=100"
)
readr::write_lines(gh_api_response, file = "gh_api_response.txt")

with more information on what kind of machine the file was generated.

I've removed the additional whitespace in the GH API response. Should work now.

Can you test again @bryanhanson?

[bryanhanson]

This works now on my machine.

@cbeleites We are waiting for your review (and approval).

I get other errors locally, but #6 works now.
