use /__api__/v1/timezones rather than /__api__/timezones (2024.09.0)

[aronatkins]

The Connect 2024.09.0 release publicizes the time zone enumeration API.

connectapi::get_timezones() needs to call this new endpoint when available and call the unversioned endpoint otherwise.

connectapi/R/schedule.R

Lines 339 to 345 in bfefb00

	get_timezones <- function(connect) {
	raw_tz <- connect$GET(unversioned_url("timezones"))
	tz_values <- purrr::map_chr(raw_tz, ~ .x[["timezone"]])
	tz_display <- purrr::map_chr(raw_tz, ~ glue::glue("{.x[['timezone']]} ({.x[['offset']]})"))
	return(as.list(rlang::set_names(tz_values, tz_display)))
	}

The payload is unchanged; only the request path is different.
