Update dependencies

[easingthemes]

Description

• Update nodeJS version to LTS (v20)
• Update all GH Actions plugins
• Update npm dependencies
• Removed eslint dependencies, since they are now added as a peerDependencies in @adobe/eslint-config-aio-lib-config

BREAKING CHANGE:

• Since dependencies are update with major version we need to change major version also, although this package itself doesn't have any breaking change.

How Has This Been Tested?

• Lint, Unit Tests
• Local AEM with WKND content e2e tests

Types of changes

• Bug fix (non-breaking change which fixes an issue)
