feat: /rename command (#583)

* feat(rename): add /rename command

- implement the /rename command to allow staff to change the name of a topic
- validate that the new name is between 1 and 100 characters
- return appropriate success or error messages based on the validation

* refactor: ??

* fix(i18n): lowercase command name

* fix: consistency

* style: sort & format `en-GB.yml`

* feat: log rename
