docs: add asdf as way to install

[vthiery]

What does this PR do?

Document how to install stratus-red-team using asdf.
I have also slightly changed how installation methods are listed for clarity.

Motivation

Using asdf and the plugin I wrote for stratus-red-team is a convenient way to use / test different versions of stratus-red-team.

Thanks for the contribution! I'm happy to add asdf support, but I'd like to have the plugin repo as part of the same repo. Is there a way to add it e.g. in a subfolder?

I believe that the "right" way to maintain asdf plugins is the way it is now: separate from the actual tool.
I have raised a PR to add the plugin to the plugins directory: asdf-vm/asdf-plugins#971

If we want more assurance around the maintenance of the plugin, I am happy to transfer ownership to the asdf--community .

What do you think?

[christophetd]

Transfering to asdf-community would be optimal, thank you

Let me proceed with the transfer then and I will update this PR accordingly.

Hi @vthiery, still eager to merge this, let me know when the transfer happens! Thanks

[vthiery]

Hi @christophetd, I'm still waiting on the asdf-community to initiate the transfer asdf-community/infrastructure#149

[christophetd]

Thanks! I left a comment in the linked PR as well

[vthiery]

@christophetd the repository has been transferred.

Thanks @vthiery ! Do you have any thoughs on what we should do when a new version of Stratus Red team gets released? I.s. how to bump the asdf version, and how we could automate this?

[vthiery]

@christophetd there is nothing to do from your side as the asdf plugin will be able to retrieve all the releases, including the "latest" as soon as it's released.

As a user, one can simply use asdf install stratus-red-team latest to get the latest release.
If one want a specific version, asdf install stratus-red-team 2.15.0 would be the way to go.
Users may also do asdf list all stratus-red-team to list all the versions available.

Bonus tip: one can shorten the plugin name when adding it to avoid repeating "stratus-red-team". E.g. asdf plugin add stratus https://github.com/asdf-community/asdf-stratus-red-team.git and then asdf list all stratus.

Amazing! Thanks for all the work around this
