Find further live awesome lists to submit Fallout to

### Problem

The .NET list ecosystem is mostly frozen. See the skip list in #599. Only a handful of lists still merge contributions, and a submission is now open on each one found so far. Extra reach needs targets outside the .NET-specific lists.

### Outcome

A short list of curated lists that still merge contributions and where a Fallout entry is on topic, with a submission open on each.

### Acceptance criteria

- [ ] Each candidate is judged by the date of its last merged pull request, not its last push. A recent push is often a bot regenerating the file.
- [ ] Each candidate has a section where a C#/.NET build system genuinely belongs. Do not submit off-topic entries.
- [ ] A submission is raised for every candidate that passes both checks.

### Notes

Submitted so far, each with its own sub-issue: #602 (pditommaso/awesome-pipeline) and #604 (ligurio/awesome-ci).

Assessed and rejected:

- `cicdops/awesome-ciandcd` — 2000 stars, but the last merge was 2022-08.

Lesson from ligurio/awesome-ci: do not rule a list out on its title alone. It calls itself a list of continuous integration *services*, but the table already contains frameworks (Dagger, Vela, Tekton). Read the actual rows before deciding a list is off topic.

Part of #599.
