Admin dashboard best seller time period documentation is incorrect

[nnanel]

Issue in ./help/getting-started/admin-dashboard.md

The documentation says "The five best-selling products during the specified time period." however, there is no time period to specify. When comparing this report with the Reports > Products > Best sellers, we can see that the top 5 products are from all time.

The documentation should say "best seller of all time" without a "the time period selected"

The same should be checked for most viewed products, new customers and customers.
