Incorrect indentation of ^ inverted section tags in Handlebars/Mustache code

Fix indentation of ^ inverted section tags in Handlebars/Mustache code

Handlebars allows for ^ tags, like its precursor Mustache. They effectively do the same as the Handlebars #unless helper.

https://mustache.github.io/mustache.5.html#Inverted-Sections

Input

The code looked like this before beautification:

{{#unless foo}}
{{bar}}
{{/unless}}
{{^foo}}
{{bar}}
{{/foo}}

Expected Output

The code should have looked like this after beautification:

{{#unless foo}}
  {{bar}}
{{/unless}}
{{^foo}}
  {{bar}}
{{/foo}}

Actual Output

The code actually looked like this after beautification:

{{#unless foo}} // The #unless block is indented correctly.
  {{bar}}
{{/unless}}
{{^foo}}
  {{bar}}
  {{/foo}} // Incorrect indentation that cascades to following lines.

Steps to Reproduce

options.indent_handlebars = true;

Environment

OS: any
