Improved documentation around argument default values and basic auth example

[Sovietaced]

It was surprisingly challenging for me to get going with basic auth. The default values of the arguments are not configured and it was not clear that I would have to explicitly disabling request signing in order to get basic auth to work (was receiving 403s).

Given that this project uses terraform-plugin-docs to manage its documentation, it appears that the behavior to document the default value is not yet supported unfortunately. hashicorp/terraform-plugin-docs#65

Feels absurd to me that the issue has been laying around for 2 years so I'll just work on adding a basic auth example :(

Ready for review: #114
