This paper doesn’t say they are increasing.
<https://arxiv.org/pdf/2308.07966.pdf>

"We see a gradual increase in Chromium-originating queries from 2013 through 2020, followed by a sharp decline after 2020 following a change to Omnibox’s probing process."

In addition to the link from Peter we also see a significant drop in UDP query packet-sizes 16-31 and 32-47 starting around January 2021.

I think it’s fair to say that Chromium queries peaked at the end of 2020 and have declined since then.
