Reexport queryparams from URIs/HTTP instead of redefining it

[frankier]

HTTP.jl already defines queryparams in the URIs.jl namespace. See: https://github.com/JuliaWeb/HTTP.jl/pull/1012/files

HTTP can just re-export this and then there will be no conflict if someone tries to import URIs themselves. Everything will be sorted out by dispatch.

We will need to change the HTTP.jl compat to 1.8. See https://github.com/JuliaWeb/HTTP.jl/blob/master/CHANGELOG.md#v180---2023-04-27
