#' eLTER get_site_observedProperties function
#' @description `r lifecycle::badge("stable")`
#' This internal function obtains the list of observed properties measured
#' in the eLTER site through the DEIMS-SDR sites API.
#' @param deimsid A `character`. It is the DEIMS ID of the site from
#' DEIMS-SDR website. DEIMS ID information
#' \href{https://deims.org/docs/deimsid.html}{here}.
#' @return The output of the function is a `tibble` with main features of the
#' site and the observed properties collected.
