fix: preserve indentation for multiline dicts

[johnsfuller]

Fixes #93.

Summary

This updates the HubL printer so multiline dicts inherit the indentation of the HubL tag that contains them. The previous printer emitted {{ ... }} output expressions and inline {% set ... = ... %} tags without aligning nested multiline docs to the enclosing tag column, so dict entries could be printed flush with the page instead of under the expression.

Example

Input from prettier/tests/dicts.html:

{# a dict in a set tag that should line up #}
{% set test_object = {
    position: "footer",
  defer: true
}%}

{# a dict as a param #}
  {{ require_js(get_asset_url("../../scripts/super.hubl.js"), {
  position: "footer",
  defer: true
}) }}

Formatted output:

{# a dict in a set tag that should line up #}
{% set test_object = {
  position: "footer",
  defer: true
} %}

{# a dict as a param #}
{{ require_js(get_asset_url("../../scripts/super.hubl.js"), {
  position: "footer",
  defer: true
}) }}

The fixture also includes a macro call with multiple dict arguments to cover output expressions with more than one object parameter.

Validation

npm test
npx prettier prettier/tests/dicts.html --parser hubl --plugin ./prettier/dist/src/index.js
