HTTP.download() does not automatically decode Content-Encoding

Issue

When calling HTTP.get() on a resource with Content-Encoding: gzip, the response is automatically decoded for me:

julia> using HTTP
       io = IOBuffer()
       r = HTTP.get("https://httpbin.org/gzip", response_stream=io);
       println(String(take!(io)))
{
  "gzipped": true, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip", 
    "Content-Length": "0", 
    "Host": "httpbin.org", 
    "User-Agent": "HTTP.jl/1.7.3", 
    "X-Amzn-Trace-Id": "Root=1-62d6f292-06e09add2b03b541490576d4"
  }, 
  "method": "GET", 
  "origin": "75.172.111.107"
}

Using HTTP.download(), it does not:

julia> using HTTP
       HTTP.download("https://httpbin.org/gzip", "/dev/stdout"; update_period=Inf);

As far as I found, this is a regression introduced since v1.0.0, for files that could be downloaded correctly without compression

the thing is:

1. Auto decompress gzip-encoding response bodies #838 implemented gzip decompression for HTTP.get but not for HTTP.download
2. Start filling out client.md, websockets.md, and server.md doc guides #851 set "Accept-Encoding" => "gzip" as default header (R44-R46)

it works for me immediately by either:

1. simply run pkg> pin HTTP@0 to use v0.9.17
2. counterintuitively though, use HTTP.download(decompress = false, args...)
