Remove run example from CLI documentation

[ljz572000]

The Spring Boot CLI version 3.0.0 hasn't the "run" command. But the spring-boot-reference document still has that.

>spring run app.groovy  
'run' is not a valid command. See 'help'.

>

>spring help
usage: spring [--help] [--version] 
       <command> [<args>]

Available commands are:

  init [options] [location]
    Initialize a new project using Spring Initializr (start.spring.io)

  encodepassword [options] <password to encode>
    Encode a password for use with Spring Security

  shell
    Start a nested shell
  shell
    Start a nested shell

Common options:

  --debug Verbose mode
    Print additional status information for the command you are running


See 'spring help <command>' for more information on a specific command.

What's the alternative command?

[scottfrederick]

@reasonpun There is no replacement for the Spring CLI run command in Spring Boot 3.0. See #32263 for the justification.
