chore: automate devcenter documentation updates

[k80bowman]

This PR completes the github action for updating our devcenter CLI commands documentation. Once we are sure this works, I will add it to our deploy workflows.

Notes

• There is a problem with all but one of the v5 plugins where the oclif readme command does not add the link to the code for each command in the CLI repo. This should be resolved when we release v9 of the CLI, so we have decided to leave it for now.
• This adds listings for the plugins:install, plugins:uninstall, and version commands that were not previously included.

Testing

Before pushing the new documentation to devcenter

• Check the artifact in this workflow run and validate that it contains the correct commands.
