SBOM Generation is failing

[lbussell]

Here's an example of the failure from the dotnet-docker-nightly pipeline:

/usr/bin/pwsh -NoLogo -NoProfile -NonInteractive -Command . '/mnt/vss/_work/_temp/ec43ae6b-0059-4dad-929b-0d418318796c.ps1'

Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

##[error]PowerShell exited with code '1'.

This is odd because there doesn't seem to be a new version of the Manifest Generator Task that would cause a regression. The current version is 0.197.56 which is the same version that existed on builds that were working.

Also, this failure is inconsistent - here's two legs of the same build that are failing/passing the SBOM stage

Passing: https://dev.azure.com/dnceng/internal/_build/results?buildId=2386549&view=logs&j=9aada89a-2e24-5acb-2807-6900158b9cce&t=019042b9-3668-5c2d-d087-47aa8f6af465

Failing: https://dev.azure.com/dnceng/internal/_build/results?buildId=2386549&view=logs&j=5451b624-d93a-5e9f-b2ab-9f4f54898441&t=6a4dd7b5-b345-5561-496f-4b7a1bc4fa21

This has not been a problem in the past month.

This was fixed by the changes in the Generate SBOMs step from https://github.com/dotnet/docker-tools/pull/1215.
