visibility and limiting on using testhelpers.getBuffaloUrl

[sio4]

While testing #96, the test case for InstallOldBuffaloCMD() keeps failing but it's not easy to find the reason.

Found it!

The reason for the issue was 403 Forbidden. I think the api.github.com has a request rate throttling and the test called too many requests within a short period. I did DoS them :-) How about using https://pkg.go.dev/testing#hdr-Skipping?

actual  : "unexpected response for https://api.github.com/repos/gobuffalo/cli/releases/tags/v0.16.40: 403"

Maybe these:

[1] https://docs.github.com/en/rest/reference/rate-limit
[2] https://docs.github.com/en/developers/apps/building-github-apps/rate-limits-for-github-apps

https://api.github.com/rate_limit

Please take a look at this PR, merge it if it is an acceptable workaround (at least for now), then please rerun the tests for #96
