Title: [dotnet new] Skip failing test CanFilterAuthor_WithoutName due to unstable output

[v-wuzhai]

Describe the bug

The test CanFilterAuthor_WithoutName fails because the Author column in the output is sometimes truncated (e.g., shown as Blazor Mic...), which prevents a full match with the filter value "micro". This causes false negatives in assertions that expect full author names. The test should be skipped until the output format is stabilized or the test is updated to handle truncation.
