new module comma and some updates (#704)

update:
- cwdhist: openeditor changed from alt+e to alt+o
- docker: pull, push add nerdctl insecure-registry support
- docker: registry show use curl instead http get (may cause dns
resolution problems)
- git: status `table -n` changed to `table -i`

new module: comma

Similar to `pwd-module`, but supports completion and description through
custom data formats
- `,` or `*` need to be exported in order to use `,` directly
- Directly execute `,` to create a new template file or edit an existing
file
- Custom tasks are written in `$env.comma` and can be nested
- Generate completions based on the structure of `$env.comma`
- You can use closure to customize completion
- In `$env.commax.act` of default closure, you can receive parameters
after the current position
- In `$env.commax.cmp` , you can receive the parameter before the
current position
