Add list-bin support for scripts.

[bacchanalia]

Small PR to add script support for list-bin. It includes a test.
Because of #7774, I do not believe there is any documentation that needs to be updated.

Related: #7073

Issue 1: I checked the test output but it does not contain the path to the binary. I'd expect that list-bin produces this path. It is actually doing that for the released cabal-install-3.8, but not on master, likely due to

• cabal list-bin is broken #8664

Anyhow, the test should really include the produced executable path, and I think it didn't due to #8400.
That the path is not included in the test output seemed to have slipped your attention and also passed unnoticed through the review (ping @Mikolaj @jneira).

Because of #7774, I do not believe there is any documentation that needs to be updated.

Issue 2: There is documentation of list-bin now, but does not include your use case with scripts. This is

• Mention of support for scripts for list-bin. #7986

Would you be able to supply this documentation now to close #7986?

Indeed I missed the test output problem and the above suggestions make sense to me.

@bacchanalia : I don't understand how this assertOutputContains succeeds with above output (that does not contain something resembling a cacheDir). But apparently it does. How?
