Add EasyAlign support for HCL files

[jay7x]

This allows to use EasyAlign in addition to Tabularize for HCL settings alignment

As you might have noticed, this repository is basically inactive - mostly because it's "done" rather than because it's "abandoned" - but still, I am reluctant to add features or expand existing ones: especially features that I don't use myself in code that I don't understand!

(And to be honest I never really understood the appeal of Tabularize or similar in a filetype that has an opinionated formatter. It's all going to look the same once you terraform fmt it, surely?)

So my immediate reaction is to lean towards "thanks, but no thanks". Would that be very annoying?

I'd be happy to use the terraform fmt but..

$ terraform fmt terragrunt.hcl 
╷
│ Error: Only .tf and .tfvars files can be processed with terraform fmt

If you know any HCL formatter please share, I'd go with it instead..

well.. after some experiments I found I can do terraform fmt - to format the terragrunt HCL.. maybe I'll create my own function to format on save instead then.. let's close the PR
