[IMP] base version: lower from warning to info

In Odoofin, we don't have a master branch, we always update current
stable version (17.0 at the moment) through module migration scripts.
This was previously handled by internal at each major version update.
We now handle the scripts in the accounting team, thus have an upgrade
CI.

The warning modified in this PR seems to be legitimally raised, since base
is not changed, it is probably skipped in the update even if we do the upgrade
with `-u all`. The warning level is preventing us to merge without admin rights,
thus we propose to lower the warning to info level.

Example of build with this warning: https://runbot.odoo.com/runbot/build/63601210

closes #95
