Update to 1ES Pipeline Template v2

[Copilot]

The v1 1ES Pipeline Templates use deprecated linux-1es-gpt-prerequisites artifacts, causing non-blocking errors in builds on NetCore1ESPool-Svc-Internal/1es-ubuntu-2204.

Changes

• Updated .vsts-ci.yml to reference v2 templates (v2/1ES.Official.PipelineTemplate.yml and v2/1ES.Unofficial.PipelineTemplate.yml)
• v2 templates include updated prerequisites using linux-1es-pt-prerequisites-v2

 extends:
   ${{ if and(ne(variables['Build.Reason'], 'PullRequest'), eq(variables['Build.DefinitionName'], 'dotnet-installer-official-ci')) }}:
-    template: v1/1ES.Official.PipelineTemplate.yml@1esPipelines
+    template: v2/1ES.Official.PipelineTemplate.yml@1esPipelines
   ${{ else }}:
-    template: v1/1ES.Unofficial.PipelineTemplate.yml@1esPipelines
+    template: v2/1ES.Unofficial.PipelineTemplate.yml@1esPipelines

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• aka.ms
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Sounds like they are going to fix this for us. We really need them to make it so if we get a warning in our pipelines, it's actionable and the message is directly assignable to copilot.
