ci: fix lychee link-checker failures

Update .lychee.toml to exclude the following patterns:
- ARM domains (developer.arm.com, infocenter.arm.com) which return 403
  Forbidden due to anti-bot protections in CI.
- Local TCP addresses (192.168.1.10) which are unsupported by the
  link-checker tool.
- The .lychee.toml file itself, to prevent the tool from recursively
  checking its own regex exclusion patterns as valid URLs.
