Add offset parameter

[cpswsg]

Overview

This PR adds the offset parameter functionality, similar to how it works in the default Statamic collection tag. This allows users to skip a specified number of results in the output.

Changes

• Added offset parameter handling in src/Events.php and src/Tags/Events.php
• Updated documentation to include the new parameter

Example Usage

{{ events:upcoming collection="events" limit="10" offset="2" }}
  {{ start }} {{ end }} {{ has_end_time }}
  ...other entry data
{{ /events:upcoming }}
