Lean down CLI for remote component repositories

Description of feature

When using a remote component repository, most modules and subworkflows commands need to be augmented with --git-remote or -g and if needed the --branch. It ok when installing multiple modules or subworkflows back-to-back, the command line still in history.

In my lab, however it has become increasingly heavy, since most of our modules and subworkflows live outside of nf-core repositories for now and the creation of a new component requires to call create, test and lint commands a lot. It would be nice to have a programmatic way to configure those remotes, may it be in nf-core configuration directly, or through the CLI environment.

I'm not sure the best way to do this, environment variables seems easy to do, but XDG_CONFIG_HOME is maybe a more standard way to do it. In any case, let's talk about it !

Start by reviewing the CLI's modules and subworkflows create, test, and lint commands, especially their existing --git-remote/-g and --branch options. Determine how a persistent remote configuration should interact with those flags and define a clear completion check for repeated remote-component operations.
