Update Fedora references in YML files from 42/40 to 43/42

[Copilot]

Updates Fedora version references in CI/CD pipeline configuration files for Helix testing infrastructure.

Changes Made

• Fedora Latest: Updated from version 42 to 43
• Fedora Oldest: Updated from version 40 to 42

These changes update the Docker image references and platform definitions used by the Helix testing infrastructure to test against newer Fedora versions.

Files Modified

• eng/pipelines/helix-platforms.yml - Updated both latest and oldest Fedora version definitions
• eng/pipelines/libraries/helix-queues-setup.yml - Updated Fedora reference used in extra-platforms CoreCLR testing

Validation

• ✅ YAML syntax validated successfully
• ✅ No security vulnerabilities detected (CodeQL scan)
• ✅ Changes follow established patterns in the configuration files

Original prompt

Update Fedora references in *.yml files. I believe there are only two relevant ones. They can be found by searching for "fedora-".

Where there is min and max, use 42 and 43, respectively. Where there is a single choice, use 43.

@copilot I'm wondering why the build is being run before updating any files. Or am I missing the edits?

You're right - I created the initial plan commit prematurely without making any file changes. I'll now make the actual updates to the Fedora references in the YML files and commit those changes properly.

@copilot Close. Oldest should be Fedora 42 and newest Fedora 43.

Fixed in c3c4e7f. Updated oldest from 41 to 42.

This looks clean for Fedora on PR and Extra Platforms. I don't see any linux-x64 failues.

Main place to look: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1207203&view=logs&jobId=803b4c9b-c8dc-5f8e-c2da-4890c86ff82f&j=803b4c9b-c8dc-5f8e-c2da-4890c86ff82f&t=b981e634-422d-532f-0103-2cf28078ad75

I saw a break for Ubuntu 26.04:
https://dev.azure.com/dnceng-public/public/_build/results?buildId=1207203&view=logs&jobId=f34c4883-3ffa-561e-aa56-47727d75db21&j=f34c4883-3ffa-561e-aa56-47727d75db21&t=94086b59-3b57-5d7f-6f81-edbeaf0f6cce

That break is unrelated to this PR. That same leg passed on #121730. I double checked just now. Just recording here if it turns out that root cause is the other PR. I looked at a later run in the same pipeline. I don't see the failure but do see the 26.04 queue. I'm going to ignore this problem until I hear more.

Ready for approval?
