Handle multiple_token flag in generate-command-help.rb (#10822)

Currently generate-command.help.rb dose not handle the
multiple_token flag, handle this flag in this PR.
The format is the same as redis-cli rendering.
```diff
- bitfield_ro key GET encoding offset [encoding offset ...]
+ bitfield_ro key GET encoding offset [GET encoding offset ...]
```

Re run generate-command-code.py which was forget in #10820.
Also change the flag value from string to bool, like "true" to true
