PR Description:

This PR updates the no-style-please theme to maintain compatibility with the latest versions of its dependencies. The changes made in this PR are as follows:

1. Ruby 3.4.1 (Stable):

   • Updated the Gemfile to include the following dependencies required by Ruby 3.4.1:
     • gem "csv"
     • gem "bigdecimal"
     • gem "base64"
     • gem "logger"
   • csv, bigdecimal, base64 were loaded from the standard library, but are not part of the default gems starting from Ruby 3.4.0.
   • logger was loaded from the standard library, but will no longer be part of the default gems starting from Ruby 3.5.0.

2. Jekyll Version:

   • Updated jekyll version to 3.10.0 to ensure compatibility with GitHub Pages.

3. Jekyll Feed:

   • Updated jekyll-feed to 0.17.0 to remain in sync with the latest stable release of the plugin.

4. SCSS Updates:

   • The SCSS files have been updated to replace the deprecated @import rule with the newer @use rule.
   • This change ensures the theme follows the latest best practices for SCSS, but it does result in the need to manually compile the SCSS to CSS. Consequently, the CSS file size has increased slightly from 1KB (when using @import) to accommodate the changes introduced by @use.

5. Bug Fixes:

   • This PR also fixes Cannot use no-style-please on Jekyll above 3.8.7 #12 , improving the overall functionality and stability of the theme.
