GitHub Action versioning

[danieljurek]

Versioning for azure/setup-azd should follow a versioning scheme that allows users to float the major and minor versions.

For example:

When releasing a new version of the installer (e.g. v1.2.3) we should also create tags v1 and v1.2 which will always point to the latest release for major and major+minor versions. So when we release v1.2.4 then both v1 and v1.2 point to v1.2.4.
