Variable tooltip descriptions not formatted correctly with heredocs

[kriswuollett]

Tooltip for variable descriptions that use heredoc is not formatted correctly when indented, or not shown at all if not indented. It could be related that Terraform itself may include the heredoc delimiters in its console output, but for an IDE it should be formatted properly. I'm not expecting the level of functionality like the IntelliJ Java reference information, but I do expect that embedded newlines and tabs should be processed along with those implied from heredoc should be applied to get a readable description in HCL tooltips. A nice to have would be Markdown formatting.
