FR/Suggestion: create ASDF plugin

[pataquets]

First of all, thanks for sharing such a tool.

Is your feature request related to a problem? Please describe.
Not as much a problem, but just a convenience. Installing is easy enough, but adding it to asdf would make it easier and, additionally, improve updating.
What is asdf?

Describe the solution you'd like
Add an asdf plugin to support GQL installation.
Create a Plugin

Describe alternatives you've considered
None.

Additional context
None.

Also, I've discovered a handful of new dev tools by browsing asdf plugin list. This would help GQL achieve more visibility, too.
