 The test
 `\Tests_Image_Editor_Imagick::test_remove_pdf_alpha_channel_should_remove_the_alpha_channel_in_preview()`
 was introduced in #39216 / [56271].

 On some hosting providers, this test appears to be failing with errors
 such as this:

 {{{
 Tests_Image_Editor_Imagick::test_remove_pdf_alpha_channel_should_remove_the_alpha_channel_in_preview
 The intermediate size could not be retrieved.
 Failed asserting that false is of type "array".

 /tmp/wp-test-runner/tests/phpunit/tests/image/editorImagick.php:680
 }}}

 Examples:

 https://make.wordpress.org/hosting/test-results/r57848/wetopibot-r57848/

 We should investigate this failure to see whether it's an issue in core or
 with the hosting provider.

 The test mentions "Ghostscript version >= 9.14", so maybe it's just a
 matter of skipping the test if the installed Ghostscript version (`gs
 --version` I think) is older than that.
