Automate version numbering using Semantic Versionning (semantic-release-gitlab)

https://www.npmjs.com/package/semantic-release-gitlab

from https://semver.org/ :
  Given a version number MAJOR.MINOR.PATCH, increment the:

  - MAJOR version when you make incompatible API changes,
  - MINOR version when you add functionality in a backwards-compatible manner, and
  - PATCH version when you make backwards-compatible bug fixes.

For MAJOR, choosing 6 is obvious.

From Minor it's not clear. This number is supposed to reflect the number of
add functuionnality, so starting at 0 is not great.

The current version is 1.762, but starting at 762 would be wrong too,
as most do not deals with new functionnalyties.

In a ideal word, I should use the log and tag every commit tha deals with a new
functionnalyty, but there is a lot of commits (762).

Hence I,'ve decided to choose 100.
