Convert Text to Outlines.js

/* 
    Convert Text to Outlines.js

    Updated: October 23 2022, Sara Linsley (InDesign 2022)
    
    ----------------

    Purpose:
        Converts text frames in an InDesign document to outlines, given some search criteria for text in the Find/Replace dialog.

    Installation instructions here: https://github.com/saraoswald/Manga-Scripts#how-to-use-scripts-in-indesign

    Instructions: 
        - Open a document in InDesign.
        - Open the Find/Replace dialog (Ctrl/Cmd + F), and provide some search criteria. E.g., Find Format: "CCMeanwhile + Regular"
        - Run this script.
        - Confirm that the number of text frames that's listed in the dialog that pops up seems correct.

    // (progressBar.minWidth does absolutely nothing)
