Add Hol1kgmg repository

[Hol1kgmg]

The following points apply when adding a new repository to repos.json

• I ran ./bin/nur format-manifest after updating repos.json (We will use the same script in github actions to make sure we keep the format consistent)
• By including this repository in NUR, I confirm that any copyrightable content in the repository (other than built derivations or patches, if applicable) is licensed under the MIT license
• I confirm that meta.license and meta.sourceProvenance have been set correctly for any derivations for unfree or not built from source packages

Additionally, the following points are recommended:

• All applicable meta fields have been filled out. See https://nixos.org/manual/nixpkgs/stable/#sec-standard-meta-attributes for more information. The following fields are particularly helpful and can always be filled out:
  • meta.description, so consumers can confirm that that your package is what they're looking for
  • meta.license, even for free packages
  • meta.homepage, for tracking and deduplication
  • meta.mainProgram, so that nix run works correctly

I had requested a review of this PR with GitHub Actions failing. I have made revisions, so please review it again.

• Revert "Add new repository entry for Hol1kgmg in repos.json" #1055

It doesn't look like any packages have been added.

Apologies for the accidental close just now (reopened), and for the long delay overall.

@Pandapip1 addressing your earlier review comment — packages (herdr, yaskkserv2) have now been added to the repository, so it should no longer appear empty.

To recap the history: the original entry was merged in #1053 but reverted in #1055 due to an eval failure. I've since fixed the repository (verified with a full nix-env -f . -qa --json --meta evaluation completing without errors) and rebased this branch onto the latest main to resolve the merge conflict.

This should be ready for review again — thank you for your patience.
