Add `base64` gem as dependency for Ruby 4.0+ compatibility

[ahogappa]

Problem

Liquid gem (~> 5.0) internally uses require "base64" in standardfilters.rb, but does not declare base64 as a dependency in its gemspec.

Starting with Ruby 4.0, base64 is no longer included in the default gems. This causes a LoadError when Liquid's standard filters are loaded on Ruby 4.0+.

Upstream issue: Shopify/liquid#1772 (open since Dec 2023, still unresolved as of Liquid 5.11.0)

Goal

Add base64 to taski's gemspec as an explicit dependency to work around the missing dependency in Liquid.

spec.add_dependency "base64"

Notes

• This is a workaround for an upstream Liquid bug
• Can be removed once Ruby 3.3 deprecation warnings: base64, bigdecimal will no longer be part of the default gems Shopify/liquid#1772 is resolved and taski upgrades to a fixed Liquid version
