build: Use Gradle version catalog

This pull request updates the Gradle build configuration to use the new version 
catalog functionality, which allows us to store our dependency versions in a 
centralized file located at `gradle/libs.versions.toml`. 

Our previous approach stored the versions in `gradle.properties`. 
The benefit of this approach however is that (1) it will be supported by 
Gradle and (2) it allows us to access dependencies safely.
