Fix file path issue in check_fonts_installed method

[irfano]

What does it do?

This fixes an issue with accessing a file in check_fonts_installed method. Before, calling this from WCAndroid resulted in the following error:

No such file or directory @ rb_sysopen - playstoreres/assets/style.css

Checklist before requesting a review

• Run bundle exec rubocop to test for code style violations and recommendations
• Add Unit Tests (aka specs/*_spec.rb) if applicable
• Run bundle exec rspec to run the whole test suite and ensure all your tests pass
• Make sure you added an entry in the CHANGELOG.md file to describe your changes under the appropriate existing ### subsection of the existing ## Trunk section.
• If applicable, add an entry in the MIGRATION.md file to describe how the changes will affect the migration from the previous major version and what the clients will need to change and consider.

@AliSoftware, could you help me choose the right milestone for this PR and #614? I want to include these fixes in the next WCAndroid and WCiOS releases.

Cc @iangmaia since I'm kinda afk today

• I think we could remove the Danger rule about milestone in this repo as we don't really use them for this tooling repo
• Can you make a new release so that @irfano can point to it in WC repos?

[AliSoftware]

I've prepared a new release in #616

@irfano Version 12.3.3 has now been released and published to RubyGems, so you should be able to update the reference in WC repos 👍
