Bug 1669378 [wpt PR 26001] - Do not test `font-display: auto` in WPT, a=testonly

Automatic update from web-platform-tests
Do not test `font-display: auto` in WPT

The spec (*) intentionally leaves the behavior of `font-display: auto` as
user-agent-defined, allowing different browsers to use different
strategies. Therefore, the behavior will not be interoperable and should
not be tested in WPT.

This patch removes the related tests from
css/css-fonts/font-display/font-display.html
