Bump guava from 30.1.1-jre to 32.1.2-jre

This fixes insecure permissions of files created in the temporary
directory: https://nvd.nist.gov/vuln/detail/CVE-2023-2976

Version 32 is binary compatible with version 30 because only the
GWT jar has breaking changes:
google/guava#2575 (comment)

I run CI for these repositories and found no regressions:

* vertx-config: https://github.com/julianladisch/vertx-config/actions/runs/6289869333
* vertx-grpc: https://github.com/julianladisch/vertx-grpc/actions/runs/6289478128
* vertx-zookeeper: https://github.com/julianladisch/vertx-zookeeper/actions/workflows/ci-5.x.yml

The failures in vertx-zookeeper are not regressions because they
exist with 30.1.1-jre.

I found no other Vert.x repository that uses Guava and hasn't
been removed for Vert.x 5.

Obsoletes #118
