Instructions on installing hasura-cli using asdf-vm

### Is your proposal related to a problem?

We have a lot of tools we use including the hasura-cli and would like to keep the version consistent with team mates.
Currently everyone would have to manually keep the vesion in sync.

### Describe the solution you'd like
We achieve this using https://asdf-vm.com/ which adds a `.tool-versions` file to the project (not hasura but user's project)
where we can set the version used and everyone just get's the same version and even in added to project's git history
I have also created the [repository](https://github.com/gurukulkarni/asdf-hasura#install) itself that helps install hasura-cli and would like to help hasura-cli users with the easy installation and use :)

### Describe alternatives you've considered
alternative is maintain the version manually with communication. Not sue if this is feasible for remote teams.

Start with the hasura-cli installation instructions and the linked asdf-hasura repository. Document how users can install hasura-cli through asdf-vm and pin the version in a project's .tool-versions file; done when the steps and version-consistency workflow are clear.
