Update Compatibility with Commerce 3.0 & Drupal 11

Problem/Motivation

This theme has a composer.json file which contains a few limitations that make this theme incompatible with its mission. For instance, Commerce 3.0 is in beta, but this theme's composer.json limits it to Commerce 2 (which won't work with D11). The theme is not D11 compatible and limits the bootstrap version to 3.7 (EOL in 2019). D10 will soon go end of life,

Proposed resolution

Update the theme to work with Commerce 3, D11 and Bootstrap 5.
