Using stylesheet tag with hyphens results in incorrect "tag was never closed" SyntaxError

Describe the bug

theme-check erroneously claims that stylesheet tags using hyphens are not closed.

Expected

{%- stylesheet -%}
    <CSS Rules>
{%- endstylesheet -%}

Should not result in any reported errors.

Actual

theme-check response:
'stylesheet' tag was never closedtheme-check[SyntaxError](https://github.com/Shopify/theme-check/blob/main/docs/checks/syntax_error.md)

Stack trace

none

Debugging information

• OS Linux
• theme-check 1.11.0

Additional context

Removing the hyphens like below fixes the error however:

{% stylesheet %}
    <CSS Rules>
{% endstylesheet %}

Even if there is a rule that stylesheet tags should not have the new-line preventing hyphens (not stated anywhere that I am aware of), the tag was never closed error would not be the correct classification.

Reproduce the issue through theme-check using the hyphenated stylesheet and endstylesheet tags shown in the report, then trace how the parser handles those delimiters. Compare that path with the non-hyphenated example. Done means the hyphenated form produces no SyntaxError while the existing form remains valid.
