Problem Description
A follow-up to #16084.
Even if I override the msbuild build props to use x64 Hermes on ARM Windows instead of x86 Hermes (by adding this build prop that sets release\x64\hermes.exe):
<HermesCompilerCommand Condition="'$(HermesCompilerCommand)' == ''">$(HermesPackage)\tools\native\release\x64\hermes.exe</HermesCompilerCommand>
... the build still fails:

The only thing it found to be missing was Node.js. However, I do have Node.js LTS on path (it can be used directly from cmd.exe, Powershell, and gitbash), as rnc-cli info confirms, so I think the doctor command is just getting a false negative.
Steps To Reproduce
Create a new React Native Windows app and override the <HermesCompilerCommand> to use ARM Hermes, as described above.
Next, attempt a release build:
rnc-cli run-windows --arch=ARM64 --release
Expected Results
Release build should work.
