Fixes issue #5489

[dwsmart]

Fixes issue #5489 by changing these lines from:

 aliasedRequire(
                (typeof __dirname !== undefined ? __dirname : '.') +
                    '/locale/' +
                    name
            );

To:

aliasedRequire(
                `${typeof __dirname !== undefined ? __dirname : '..'}/locale/${name}`
            );

@dwsmart can you try latest develop, I merged something to fix the typeof. Also, in 2.24.0 the code was just './locale' + name, so I'm not just changing it to '../locale' + name.

@ichernev, yes latest develop version seems to have addresses the issue, not sure why it had to be '../locale' instead of ./locale' but that was required to fix. Probably my misunderstanding of something. I'll close the pull request.
Thanks!
