`docker-compose version --short` changed output from `vX.Y` to `X.Y` between v2.2.3 and 2.3.3

[rfay]

Description

docker-compose version --short always used vX.Y as its format (for example, v2.2.3). In v2.3.3 it uses X.Y (without the 'v'),

$ ./docker-compose version --short
2.3.3

Since other projects depend on this output, it should remain the same from version to version.

Steps to reproduce the issue:

Run docker-compose version --short

@rfay that's to be backward compatible with the python version
#9096

But... incompatible with all previous composer v2. And different from what docker-compose --version or docker-compose version report :)

It doesn't matter, I made DDEV be resilient with both.
