Update Windows 2022 CI images

[Copilot]

The generic Windows 2022 images provide an outdated .NET 10 SDK. Align the pipelines with the architecture-specific images used by .NET SDK CI.

• Public CI
  • Use windows.vs2022.amd64.open for build, lint, and packaging jobs.
• Internal and release pipelines
  • Use windows.vs2022.amd64 for build, SDL, packaging, SBOM, and publishing jobs.

# Public
demands: ImageOverride -equals windows.vs2022.amd64.open

# Internal
image: windows.vs2022.amd64

• Fixes Update 2022 images #2806

Any reason to not move to vs2026?

No, the AI just didn't find them. @copilot We should use the 2026 images, not these images. We're also now seeing 'Unable to locate executable file: 'bash'. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also verify the file has a valid extension for an executable file.

Updated the pools to windows.vs2026.amd64(.open) and converted the Windows lint/package Bash steps to PowerShell in 350c97a. I also removed unrelated lockfile churn from the net PR diff.

@copilot Ideally, this PR wouldn't reimplement the logic in powershell from bash. I think we need to instead look at if these images dont have bash, or if we can call bash differently in a way that works on these images. We want the diff to be minimal for version changes to the build images only plus any minimal change that makes it work - e.g. even if its having a separate yml we call that installs bash (but only if it is not actually available on the image - perhaps use other repos for compairson like dotnet/sdk?). This is evident in the new problems caused by your change:

Restored the original Bash scripts unchanged in 702e9c6. The shared setup now adds the image’s existing Git Bash directory to PATH and provisions Yarn 1.22.22 through Corepack. The rerun’s ESLint and VSIX packaging jobs both pass; the checkout/DNS failure also cleared without a code change.

Are we getting value out of using yarn instead of npm? Seems like it adds complexity.

[nagilson]

It does, I forget why we did this and things might have changed but there is some NPM limitation that made it nonfunctional, at least 2 years ago. We have to use npm too because yarn doesnt have support for vsts auth. CDK does the same thing, unless things changed.

[nagilson]

#617 outlines why, it mentions there's a VSCE limitation where it required yarn and didn't work with npm. I think it has to do with the multi-folder layout we use but not quite remember. I'm pretty sure I explained this in more detail in a comment somewhere.
