libpg-query -- new upstream version

Hi,

There is a new upstream version of libpg_query[1] and I have pushed
updated packaging to the Salsa repo[2]. This release upgrades to
Postgres 17 and is required for upgrading pglast to its latest upstream
version[3]. I have tested locally that pglast 7.0 builds successfully
with the updated packages for libpg-query.

One question that I had was around the package naming -- it looks like
the last upload renamed the libraries for the 64-bit time_t transition.
I wasn't sure if this naming was only needed for the transition or is
needed going forward. I also removed the 'Replaces' and 'Breaks' from
d/control.

Thanks,
--Bradford
