Update to pgbouncer v1.17.0 on Heroku-22 (#166)

To fix crashes/seg faults seen on Heroku-22 due to Ubuntu 22.04
now shipping with OpenSSL 3.

See:
https://www.pgbouncer.org/2022/03/pgbouncer-1-17-0
https://www.pgbouncer.org/changelog.html#pgbouncer-117x

The other stacks remain on pgbouncer 1.14.0 for now, until #150 (the reason
an earlier upgrade to pgbouncer was rolled back) can be investigated.

#165 is also open for improving the CI of this repo (since it didn't catch these
crashes), though fixing that is out of the scope of this PR, as we just need to
stop the crashes for now.

Fixes #164.
