The name column was always padded to maximum width, even if no other columns were printed.

This makes it difficult to use the output e.g. in pipelines.

Fixed for all possible columns, and with tests for two cases (regular show and show outdated).

Sort of related to #11046 (although this is not a regression, but didn't work before, either)

On macOS, if libcurl is built against SecureTransport, the platform repository will contain an invalid package name:

    % composer show --platform | grep curl
    ext-curl                           8.2.7    The curl PHP extension
    lib-curl                           8.1.2    The curl library
    lib-curl-(securetransport) openssl 3.1.1    curl (securetransport) openss...
    lib-curl-libssh2                   1.11.0   curl libssh2 version
    lib-curl-zlib                      1.2.11   curl zlib version

This change fixes it:

    % bin/composer show --platform | grep curl
    lib-curl                 8.1.2              The curl library
    lib-curl-libssh2         1.11.0             curl libssh2 version
    lib-curl-securetransport 3.1.1              curl (securetransport) openssl ...
    lib-curl-zlib            1.2.11             curl zlib version

(second column width difference comes from the Composer dev version number)

* Use static test data providers

Using non-static methods as a data providers was deprecated in phpunit
10.

* Rename abstract test class

Abstract test case classes with Test suffix are deprecated in PHPUnit
10. We also change the ArchiverTest file name to match the new class
name (ArchiverTestCase).
