'legacy' branch is mentioned in README, but apparently doesn't exist

[boldandbusted]

Describe the bug
The README.md mentions a 'legacy' branch. There's no such branch currently on this repo.

Expected behavior
Either the mention of the 'legacy' branch be removed from the README.md, or the legacy branch be added to this repo for folks not yet using Collections.

Actual behavior

less README.md
User cries when checking branch list.

OS / Environment

The environment turns very sad for everyone when they see this discrepancy in the README.md. ;)

Additional context
Thank you for all the work on this code! :) I would love to see non-Collections support, but I do understand that this is where Ansible core development is moving, for better or worse. Cheers.

I am very sorry we made you sad. After taking a look into our code I think we should be linking to an old tag in our Repo and not to a specific branch. Would this make you happy, or is your happiness entirely dependent on a special branch in this Repo? ;)

So, I hope the world is a better place now. Thank you for this great issue :)
