Pull request overview

Updates the VMR synchronization Azure Pipelines job to run on Ubuntu 22.04 build images instead of Ubuntu 20.04, aligning the vmr-sync infrastructure with current 1ES pool images (per dotnet/source-build#5481).

Changes:

• Switch the public pool image from 1es-ubuntu-2004-open to 1es-ubuntu-2204-open.
• Switch the internal pool demand from ImageOverride -equals 1es-ubuntu-2004 to ImageOverride -equals 1es-ubuntu-2204.

This is likely fine, but I hit an issue with 2204 image for vmr-scan job. As the image has .NET installed, InitializeDotNetCli step is not installing the local copy. My fix was in https://github.com/dotnet/sdk/pull/51725/changes

Thanks for calling this out :) I checked the yamls and only see references to the dotnet exe in the sync scripts:

• vmr-sync.ps1
• vmr-sync.sh

The pwsh script looks okay, but the bash script needed to be updated. I've addressed this in 4dfccfb

FYI I don't think 1es-ubuntu-2204-open works in public just yet, it's tracked by https://dev.azure.com/dnceng/internal/_workitems/edit/9365/

probably doesn't matter since we likely don't run vmr sync in public anymore
