The file subversion is no longer used in the Python API or user interface,
and is now internal to Blender.
User interface, Python API and file I/O metadata now use more consistent
formatting for version numbers. Official releases use "2.83.0", "2.83.1",
and releases under development use "2.90.0 Alpha", "2.90.0 Beta".
Some Python add-ons may need to lower the Blender version in bl_info to
(2, 83, 0) or (2, 90, 0) if they used a subversion number higher than 0.

This change is in preparation of LTS releases, and also brings us more
in line with semantic versioning.
Fixes T76058.
Differential Revision: https://developer.blender.org/D7748
We need to handle beta stage in a specific way, since it's no longer
master, but not yet 'real' rc/release stage...
For now, only point to version dir of the API doc, but no need to create
any symlink (that way, 'current' remain pointing to 2.80 release, while
'2.81' is no longer a symlink to 'master', but its own actual doc).

- for dev: /api/master/, zip file named blender_python_reference_2_79_4.zip
