Describe the bug
In getting-started/_build-system.md "Building an Executable,"   a main.swift file is referenced. My swift package command does not create a main.swift file. It is still creating a hello.swift file and it is still an executable program. Is the documentation out of date or is this a new feature?
I am using Swift 5.7.2. Was this changed in later versions?
To Reproduce
Steps to reproduce the behavior:
Run the following commands in a terminal window:
- mkdir hello
- cd hello
- swift package init --type executable
Now, inspect your hello/Sources/hello directory.
Expected behavior
According to the documentation, Using the Package Manager, there should be a main.swift file in the Sources/hello directory.
Actual behavior
There is only hello.swift in the Sources/hello directory.
