feat: Add hatch shell command

[karthiknadig]

Git Bash activated with hatch shell

Command Prompt activation using command:

For #14

Found some issues with hatch shell, essentially if you put the hatch command in the Command Prompt autoRun or Powershell profile. It seems to fail with pypa/hatch#1957

Doesn’t work for me, I asked what the intended usage is: pypa/hatch#1972

@flying-sheep I think my understanding of hatch shell was bad. I assumed --name was the name of the environment.

OK this works, but it takes a while until it executes the command for some reason.
