chore(ci): test Nim 2.2.4 and 2.2.10

[narimiran]

Summary

This PR updates the used/tested Nim version from 2.2.6 to 2.2.10.
EDIT: And, as added later on (based on #2343), it also replaces Nim 2.0.16 with 2.2.4.

Compatibility & Downstream Validation

Nim 2.2.10 allows nim-libp2p tests to also run with --mm:orc. (Not part of this PR)

References

First tested in #2148, but here is a complete search-and-replace of v2.2.6 with v2.2.10.

[Copilot]

Pull request overview

Updates nim-libp2p’s pinned/tested Nim toolchain version references from v2.2.6 to v2.2.10 across CI, docs, and Docker-based build environments to keep the repo aligned with the intended supported compiler versions.

Changes:

• Bump GitHub Actions workflows using nim_ref / matrix ref from v2.2.6 to v2.2.10.
• Update Docker images used by simulation, interop, and performance test nodes to nimlang/nim:2.2.10 variants.
• Update documentation references (README + Copilot instructions) to reflect Nim v2.2.10 support.

ERROR: failed to build: failed to solve: nimlang/nim:2.2.10-ubuntu-regular: failed to resolve source metadata for docker.io/nimlang/nim:2.2.10-ubuntu-regular: docker.io/nimlang/nim:2.2.10-ubuntu-regular: not found

pinging @moigagoo, he might know more....

[moigagoo]

@narimiran thanks for the ping!

As part of the preparation for making the images official (docker-library/official-images#19453), I've removed a lot of cruft and switched to the officially encouraged tag naming.

This should work:

FROM nimlang/nim:2.2.10 as builder

Ubuntu regular is now the only flavor being shipped so ubuntu-regular is redundant.

🤔 it seems it can't find "redis" with this change? https://github.com/vacp2p/nim-libp2p/actions/runs/24987822171/job/73165496804?pr=2339

From what I can tell, nimble fails on packages dependency resolution when running nimble install_pinned.

See if you maybe need to change some package versions in .pinned?

Yep, that indeed seems to be the case: #2348 (comment)

[richard-ramos]

@narimiran,
These errors reported in the 2.2.4 jobs... could they be related to the nim version?

   Fetching https://github.com/status-im/nim-chronos (>= 4.0.4) using git
SIGSEGV: Illegal storage access. (Attempt to read from nil?)

I am not sure what is this a75b5ee6-9934-452e-9f71-cad12620b223.sh file about.

How about leaving 2.0.16 as it were, and just add 2.2.10? (Like it was done initially in this PR, before I got the idea from #2343)

[narimiran]

On the other hand, now I've seen #2380 - so let's rebase/merge it one more time and see if that helps.

[narimiran]

IT'S GREEN!!! IT'S FINALLY GREEN!!

There were a lot of debug commits and banging my head on wall (rebased, so not visible anymore), but the problematic interop test is finally green!
And all it took was some reordering of the nimble command (see the latest commit for details).

Should be ready for merge now. (cc @richard-ramos)

lol that test was cursed, good catch on the nimble ordering, @narimiran!
