The pipelines sometimes throw "Validation-No-Executables" errors even when the manifest has an executable listed in it.

Occasionally a manifest PR validation ends up with the `Validation-No-Executables`, despite that some of the manifests visibly contain `.exe`-s in them. So either:
A) The error must be renamed.
B) The pipeline must be modified so that it can no longer throw that error if it otherwise succeeds at processing a PR that has an `.exe` in at least one of its `RelativeFilePath`-s.

Package PRs affected at the time of writing:
* #317034
* #317533
* #317709
* #318311
* #318396
* #318458
* #318587
* #318594
* #318595
* #318635

Start by tracing the manifest PR validation pipeline that emits Validation-No-Executables, using RelativeFilePath and the affected PRs (#317034, #317533, #317709, #318311, #318396, #318458, #318587, #318594, #318595, and #318635) as examples. Determine whether successful processing of a PR containing an .exe should suppress the error or whether the error name is misleading; done when the chosen behavior is consistently reflected in validation.
