#' Retrieve openresty Version Release History
#'
#' Reads <https://github.com/openresty/openresty/releases> to build a data frame of
#' openresty version release numbers and dates with pesudo-semantic version
#' strings parsed and separate fields added. The data frame is also arranged in
#' order from lowest version to latest version and the `vers` column is an
#' ordered factor.
