but some of the validation failures leak out ArgumentException from the validation in CoseHeaderMap.

There were no OOB packages with `<GeneratePackageOnBuild>` set to
`true`, so none needed to be reset to `false`.

Backport of #123450 to release/8.0

/cc @lewing @hoyosjs

## Customer Impact

- [ ] Customer reported
- [ ] Found internally

[Select one or both of the boxes. Describe how this issue impacts
customers, citing the expected and actual behaviors and scope of the
issue. If customer-reported, provide the issue number.]

## Regression

- [ ] Yes
- [ ] No

[If yes, specify when the regression was introduced. Provide the PR or
commit if known.]

## Testing

[How was the fix verified? How was the issue missed previously? What
tests were added?]

## Risk

[High/Medium/Low. Justify the indication by mentioning how risks were
measured and addressed.]

**IMPORTANT**: If this backport is for a servicing release, please
verify that:

- For .NET 8 and .NET 9: The PR target branch is `release/X.0-staging`,
not `release/X.0`.
- For .NET 10+: The PR target branch is `release/X.0` (no `-staging`
suffix).

## Package authoring no longer needed in .NET 9

**IMPORTANT**: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.
