Maybe Update Github Actions to shopify/theme-check-action@v2 to Fix theme-check issue?

[Jyrko]

Describe the current behavior

When running Github Actions CI/CD with older version of theme-check-action. In this case v1, I encountered the following error.

ERROR:  Error installing theme-check:
	ERROR: Failed to build gem native extension.

    current directory: /usr/lib/ruby/gems/3.0.0/gems/strscan-3.1.2/ext/strscan
/usr/bin/ruby -I /usr/lib/ruby/3.0.0 -r ./siteconf20250113-8-jcchfo.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.

Describe the expected behavior

Version information (Dawn, browsers and operating systems)

• Dawn Version: 15.2.0
• macOS Version 15.2

Possible solution

Update in CI/CD shopify/theme-check-action@v1 to shopify/theme-check-action@v2 in order to fix the issue.

Additional context/screenshots

Also, I have started to encounter this issue in my custom themes using older version of shopify/theme-check-action, so, I guess, it is a global problem.
