Support for indented syntax (.sass)

[zezic]

Would be good to support https://sass-lang.com/documentation/syntax/#the-indented-syntax

Of course, in the initial version, I omitted it under the assumption that the indent syntax was not widely used. However, I plan to include it in the upcoming version.

Thanks for your feedback ♥️

This will be a separate extension.(As scss tree-sitter doesn't support sass)
