Fix deadlink checker by updating HashiCorp URLs and adding ignore patterns

[Copilot]

The Dead Link Checker workflow was failing with 429 (Too Many Requests) errors from HashiCorp domains that rate-limit automated link checking tools like lychee.

Problem

The workflow was encountering rate limiting on these URLs:

• https://learn.hashicorp.com/tutorials/terraform/install-cli (in aws, azure, gcp READMEs)
• https://developer.hashicorp.com/vault/install (in aws, azure, gcp READMEs)
• https://www.vaultproject.io/downloads (in main README)

Solution

Updated URLs to current HashiCorp documentation structure:

• Changed https://learn.hashicorp.com/tutorials/terraform/install-cli to https://developer.hashicorp.com/terraform/install
• Changed https://www.vaultproject.io/downloads to https://developer.hashicorp.com/vault/install

Added ignore patterns to .lycheeignore:

• https://developer.hashicorp.com/*
• https://learn.hashicorp.com/*
• https://www.vaultproject.io/*

This dual approach ensures current documentation links are used while preventing future rate limiting issues from HashiCorp domains.

Files Modified

• aws/README.md - Updated Terraform installation URL
• azure/README.md - Updated Terraform installation URL
• gcp/README.md - Updated Terraform installation URL
• README.md - Updated Vault installation URL
• .lycheeignore - Added HashiCorp domain patterns

The deadlink checker workflow should now pass without 429 rate limiting errors.

Fixes #2240.

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 the custom allowlist in this repository's Copilot coding agent settings (admins only)
