build: Introduce gradle version catalog (#5683)

This is the first step in modernizing our gradle dependency management
by using a [gradle version
catalog](https://docs.gradle.org/8.8/userguide/platforms.html#sub:central-declaration-of-dependencies);
this PR migrates all of our bespoke `Classpaths.groovy` versions into a
standardized `libs.versions.toml`.

The biggest benefit is that dependabot will be able to submit gradle
dependency version bump PRs. As developers, we should also benefit from
greater standardization (IntelliJ works as you would expect with
autocomplete, click-through, and find usages support).

The learning curve should be relatively small.

The intention is to continue the migration to the version catalog.
Additional dependencies we declare outside of `Classpaths.groovy` should
be relatively straightforward to migrate.

Fixes #5177
