Bug: fix beautify script

[internetisaiah]

Summary

The beautify-logs.py script was slicing Antora's "pretty" logs with the assumption it knew where the maintainer was storing the git repository, so the links in the File column were breaking for some users.

The following changes have been made:

1. Antora playbooks now output logs in JSON format. This makes string slicing easier/more accurate.
2. The beautify script now creates the links in the File column by removing the text in "workspace": from "file":, then adds AsciiDoc xref syntax.

For example:

• File key: `"file":{"path":"/Users/isaiah-robinson/docs/docs/modules/automation-testing/pages/index.adoc"}
• Worktree key: "worktree":"/Users/isaiah-robinson/docs"
• After slice: /docs/modules/automation-testing/pages/index.adoc
• With AsciiDoc syntax: xref:../docs/modules/automation-testing/pages/index.adoc[index.adoc]
