build: update jOOQ & fix Gradle 9.0 compatibility issues

With the release of Gradle 9.0.0, we experienced build
failures due to deprecated access to plugin conventions
(JavaPluginConvention).
Ref: https://docs.gradle.org/9.0.0-rc-1/userguide/upgrading_version_8.html#deprecated_access_to_conventions

To address this, we:
1. Upgrade jOOQ Gradle plugin from 8.0 to 8.2.2 to
avoid deprecation warnings when using Gradle 9.0.
Ref: https://github.com/etiennestuder/gradle-jooq-plugin/releases/tag/v8.2.2

2. Upgrade jOOQ from 3.17.7 to 3.19.1 to match the
plugin version upgrade.

Note: We avoid the latest version of jOOQ because it
requires Java 21.
