bc9111a05f Use correct timestamp format for Last-Modified header (#365)
HTTP uses GMT [1,2] rather than UTC as timezone for timestamps. However,
the Last-Modified header used UTC which confused at least wget.

Before, UTC was used:

$ wget --no-check-certificate -S --spider https://cb_pages_tests.localhost.mock.directory:4430/images/827679288a.jpg
...
  Last-Modified: Sun, 11 Sep 2022 08:37:42 UTC
...
Last-modified header invalid -- time-stamp ignored.
...

After, GMT is used:

$ wget --no-check-certificate -S --spider https://cb_pages_tests.localhost.mock.directory:4430/images/827679288a.jpg
...
  Last-Modified: Sun, 11 Sep 2022 08:37:42 GMT
...
(no last-modified-header-invalid warning)

[2]: https://www.rfc-editor.org/rfc/rfc9110#name-date-time-formats

Fixes #364

Whatt I noticed is that the If-Modified-Since header isn't accepted (neither with GMT nor with UTC):

```
$ wget --header "If-Modified-Since: Sun, 11 Sep 2022 08:37:42 GMT" --no-check-certificate -S --spider https://cb_pages_tests.localhost.mock.directory:4430/images/827679288a.jpg

I would have expected a 304 (Not Modified) rather than a 200 (OK). I assume this is simply not supported and on production 304 is returned by a caching proxy in front of pages-server.
