Specify an Alias (optional input parameter)

[scolladon]

As a consumer of the github action
I want to be able to specify the alias to be used for authenticating the org
So that I can use the devhub to create package version (for example)

I also want this devhub set as global devhub

$ sfdx config:set defaultdevhubusername=<alias> --global

so that I may not have to use it outside scratch org creation

The org that is authenticated gets an alias SFDX-ENV, can't you re-use that one?

sfdx config:set defaultdevhubusername=SFDX-ENV --global
