Enable autoversionning via github actions

[ALanguillaume]

Ideally the datasets should be updated regularly.

This could be done by running a sort of CRON job on github actions every month so that
cran_monthly_package_number and may be also cran_packages_history are regularly updated.

A function must then be written that will perform the automatic version bump.

The versioning pattern could be the following:

• major: functional version only incremented if there is a change in API or added feature.
• minor.patch.dev: a date stamp of the form yy.mm.dd corresponding to the date of the automatic update.

ex: 1.22.07.01 This will be version 1 with datasets updated on July 1st 2022.
