Fix minimum width of Author column in tabular output

[v-wuzhai]

Fixes #49123

This PR increases the minimum width of the Author column in the tabular output of dotnet new search to prevent truncation of author names. This resolves a test failure caused by the output not containing the expected author string due to column width limitations.

Pull Request Overview

This PR fixes the truncation issue of author names in the tabular output by increasing the minimum width of the Author column, while also re-enabling the related integration test.

• The test for filtering by author is re-enabled by removing the Skip attribute.

• While increasing the minimum width may resolve the truncation issue, please ensure that the change is consistent with the layout of other columns and verified using long author names.
