Make it easier to run lychee locally

[Copilot]

Applied changes from open-telemetry/opentelemetry-java-instrumentation#14155 to make it easier to run lychee locally.

Changes Made

New Files:

• .github/scripts/check-links.sh - Script that allows developers to run link checking locally using Docker with the same configuration used in CI
• .github/scripts/dependencies.dockerfile - Contains lychee Docker image version for Renovate to auto-update
• .github/workflows/reusable-check-links.yml - New workflow that uses the script instead of GitHub Actions lychee-action
• .lychee.toml - Centralized lychee configuration with appropriate exclusions for this repository

Modified Files:

• .github/workflows/build.yml - Updated to use new check-links workflow instead of markdown-link-check

Removed Files:

• .github/workflows/reusable-markdown-link-check.yml - Replaced with the new approach

Benefits

• Local Development: Developers can now easily run the same link checking locally with ./.github/scripts/check-links.sh
• Consistency: Docker approach ensures identical behavior between CI and local environments
• Maintainability: Version management is centralized in dependencies.dockerfile for Renovate auto-updates
• Configuration: All lychee settings are centralized in .lychee.toml

Usage

To run link checking locally:

# Basic usage
./.github/scripts/check-links.sh

# With GitHub token for higher rate limits
GITHUB_TOKEN=your_token ./.github/scripts/check-links.sh

Requirements: Docker must be installed and running.

Fixes #27.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list
