Fix/ecip validation bundler version

[meowsbits]

https://github.com/ethereumclassic/ECIPs/actions/runs/7463320371
ecip_validator actions were failing because of a bundler version error.

Then, ecip-1100.md was failing validation because Replaced did not exist in the list of valid statuses at the ecip_validator, so I patched that and bumped the version for that here too.

ecip_validator still complains about a few Warnings, but they're not critical.
