Is your feature request related to a problem? Please describe.
There are many occasions that it is desirable to re-generate the whole table from the .all-contributorsrc file.

E.g., to avoid situation like this:

Describe the solution you'd like

Provide the @all-contributors generate command which does exactly what all-contributors generate does, to read the contributors list from the .all-contributorsrc file and re-generate the whole contributor tables specified by the files key.

Describe alternatives you've considered

I know there is CLI all-contributors generate command, but that's a big hurdle to jump over, for such a small and common ask.

In the above screenshot situation, all I did was to reorder the Emoji Key ✨ (and Contribution Types) so that they show up in correct order on my site, however, currently it seems impossible to me. Yet,

The needs to reorder the Contribution Types will be very common, especially for cases when people first contribute Bug reports, but later on they contribute code (PR), in which case, I'd like to move code to the forefront.

Please consider
