  1. Make detection for test-binary more universal 

    When running tests in verbose mode (or other options), tests involving
Cobra may fail if the test does not explicitly set Command.args to an
empty slice; in this case, Cobra defaults to using `os.Args`, which
will contain arguments passed to the test (such as `-v` (verbose)).

Commits e576205 and 1ef0913
implemented a workaround for this when running (unit) tests for Cobra
itself, but this check is specifig to Cobra (checking for `cobra.test`),
and don't work on Windows (which will have a `.exe` extension),

This patch implements a more universal check, so that users of Cobra
as a module also benefit from this workaround.

go1.21 and up provides a `testing.Testing()` utility ([1]); as the Cobra
module still supports Go1.16 and up, an alternative implementation was
added for older versions, based on golang.org/x/mod/lazyregexp [2].
