This fixes#15043
The issue is that browsers like "text/html,...,*/*;q=0.8" (see for
instance https://developer.mozilla.org/en-US/docs/Web/HTTP/Content_negotiation/List_of_default_Accept_values
)
Without this commit we end up with an array of accepted type like
`("text/html", "*/*;q=0.8)` so when we then check if the array contains
`*/*` the check fails, and we return a 406 even though the client is
able to get the response.
This commit fixes it by removing the `;q=0.8` part.
(Ideally we should not just discard that part, we should extract that
value, and order by it. See
https://developer.mozilla.org/en-US/docs/Glossary/Quality_values for
more info about that. However this could be done in a subsequent PR:
this already fixes the 406 error, which is pretty blocking)
