Add `--short` flag to odigos version command

[Eden Federman]

Currently running odigos version will print the full version of the CLI and the version installed on the current cluster.
I propose adding a new flag which can be used like: odigos version --short, this flag will return only the current version of the CLI without any additional data.
for example

> odigos install --short
v1.0.21

By implementing this feature we will be able to automatically get the current version in the Makefile without having to specify TAG env var.

I think I'm almost set to go, but there's an error on installation that does not let me test the flag.

When you execute go run . install from the code, you need to specify the version you are installing like this:
go run . install --version v1.0.27.

For official releases, the version is embedded in the CI, but for development you need to set it directly
