gh-74185: repr() of ImportError now contains attributes name and path #136770

The repr of standard exceptions usually looks as exception constructor used for creating that exception. But the repr of ImportError misses keyword arguments name and path.

>>> ImportError('test', name='somename', path='somepath')
ImportError('test',)

Proposed patch make the repr of ImportError containing keyword arguments.

>>> ImportError('test', name='somename', path='somepath')
ImportError('test', name='somename', path='somepath')

I don't know how to classify this issue and whether the patch should be backported.

I consider it an enhancement, especially if someone was sloppy with their tests and explicitly checks the repr of ImportError.

The patch also changes the repr of BaseException with a single argument. It no longer contains a trailing comma.

Including 'path' may make the repr less readable in some cases. +1 for 'name', though.

I think the issue steems from the more general bpo-27015 for which a PR is ready that fixes the repr not only for ImportError but all other BaseException subclasses that override __init__.

The PRs need to be updated. Marking as easy.
