How come a custom fork for aws-nuke?

This fork seems to have a lot more community support

https://github.com/ekristen/aws-nuke

Edit: I see in v0.40.0, this project did move to this fork but the docs still point to the old one

https://github.com/Optum/dce/blob/244520ccf58821d1e573733ad5d525b4e517ba6b/CHANGELOG.md?plain=1#L9-L12

Here are a few places that need to be switched over

https://github.com/search?q=repo%3AOptum%2Fdce+%22optum%2Faws-nuke%22&type=code

It would be good to archive github.com/Optum/aws-nuke as well

Describe the solution you'd like

Use the actively maintained fork instead of a new one with docs that reference it

• update fork to mention using the new fork
• archive fork
• update codebase to drop previous references to optum/aws-nuke
