Base tokens cause `./gradlew run` to fail with "unknown chain base"

[MrLightspeed]

Summary

./gradlew run currently aborts if the repository contains tokens/base/… entries, which blocks any Base submissions.

Steps to reproduce

1. Checkout master at e0794ee.
2. Add a Base token JSON, e.g. tokens/base/0xF0Cb96a4011A0A6F73d100c7080Bf8020D10F87a.json with valid metadata.
3. Run export JAVA_HOME=$HOME/.jdks/jdk-17.0.13+11 && export PATH=$JAVA_HOME/bin:$PATH.
4. Run ./gradlew run.

Actual result

The build fails immediately:

> Task :run
Found directory for unknown chain base

> Task :run FAILED
Execution failed for task ':run'.
> Process 'command '/home/cajohn/.jdks/jdk-17.0.13+11/bin/java'' finished with non-zero exit value 1

Expected result

Base (chain id 8453) should be accepted so the sanity run completes, just like other supported chains.
