Inconsistent naming for UpdateBrandCommand Handler

[tanczosm]

Describe the bug
This is not so much a bug as a coding mistake.

/Boilerplate/blob/master/AspNetCoreHero.Boilerplate.Application/Features/Brands/Commands/Update/UpdateBrandCommand.cs

This looks like it may have been a copy of UpdateProductCommand.cs that was altered to suit Brand. The handler inside the UpdateBrandCommand is called UpdateProductCommandHandler instead of UpdateBrandCommandHandler.

Same goes with IBrandCache repository and IProductCacheRepository.
