[dskloetc]

Description

smartcontractkit/ea-framework-js#649 improved the generator to include an example rate limiter.
Update the scripts framework version to use the new version when doing yarn new.

Changes

1. Increase "@chainlink/external-adapter-framework": "2.11.4".
2. Ran yarn.

Steps to Test

Run the output of yarn new and check src/index.ts of the new adapter.

Quality Assurance

• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant infra-k8s configuration file.
• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant adapter-secrets configuration file.
• If a new adapter was made, or a new endpoint was added, update the test-payload.json file with relevant requests.
• The branch naming follows git flow (feature/x, chore/x, release/x, hotfix/x, fix/x) or is created from Jira.
• This is related to a maximum of one Jira story or GitHub issue.
• Types are safe (avoid TypeScript/TSLint features like any and disable, instead use more specific types).
• All code changes have 100% unit and integration test coverage. If testing is not applicable or too difficult to justify doing, the reasoning should be documented explicitly in the PR.
