chore: bump AMX Mod X pin from build 5479 to 5481

[KevinTCoughlin]

Description

The Version Check workflow fails by design when a pinned upstream component has a newer release. Run 34098603808 reported AMX Mod X: build 5479 → 5481 (update available) and exited 1. Every other component (ReHLDS, ReGameDLL_CS, Metamod-R, ReAPI) was already up to date.

This bumps the AMX Mod X pin to 5481 and resyncs the docs that quote it.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Configuration change
• Infrastructure/CI update

Related Issues

Relates to the failing Version Check run above.

Changes Made

• Containerfile: ARG AMXMODX_BUILD 5479 → 5481
• README.md: stack list now says build 5481
• CHANGELOG.md: the two Unreleased entries quoting build 5479 updated to 5481

Testing Performed

• Container builds successfully: just build
• Lint checks pass: just check
• Server starts and is joinable: just up
• Manual testing performed (describe below)

Manual Testing:

www.amxmodx.org is not reachable from the sandbox this change was authored in (proxy 403), so the tarballs could not be fetched locally. The Version Check job itself HEAD-checks both amxmodx-1.10.0-git5481-base-linux.tar.gz and -cstrike-linux.tar.gz before reporting a build as the latest, so 5481 is confirmed downloadable by that run. CI on this PR builds the image against the new pin.

Checklist

• I have performed a self-review of my own changes
• I have tested that the server starts and accepts connections
• I have updated documentation if needed
• My changes generate no new warnings during build

The CHANGELOG entry claims the bump is from build 5478, but the PR’s actual pin change is 5479 → 5481, making the changelog history misleading.

🟡 Changes recommended

The updated CHANGELOG entry appears to lose the established cumulative “from” baseline (5478) and should be corrected to avoid a misleading Unreleased history.
