Disable the "should compress and save text" unit test in Chrome too

Starting with Chrome 120.0.6099.109 (shipped with Puppeteer 21.8.0+) the
unit test fails in Chrome as well. The issue is tracked in #17399, but
for now we'll only run the unit test in Firefox so we can continue to
update Puppeteer while also still having a browser in which it runs,
until we figure out why the behavior of `CompressionStream` changed.
