Implement numbering of array elements

Summary

Array Indices Display Configuration Feature

Description

This PR adds functionality to the Randomness plugin to allow users to configure how array indices are displayed when generating arrays of schemes or templates. This pull request solves the problem related to issue #582. Users can now:

1. Enable or disable index display
2. Configure the format of indices using a template
3. Use tuple-style indices for multi-dimensional arrays

Implementation Details

New Properties in ArrayDecorator

• showIndices: Boolean to control if indices are displayed (default: false)
• indicesFormat: String template for formatting indices (default: "{index}: {value}")
• useTupleIndices: Boolean to enable tuple-style indices (default: false)

UI Changes in ArrayDecoratorEditor

• Added "Show indices" checkbox
• Added dropdown for selecting index format with predefined templates
• Added "Use tuple indices" checkbox for multi-dimensional arrays
• Added help text explaining format placeholders

Localization

• Added appropriate bundle properties in randomness.properties
• Added help text explaining the format template options

Example Outputs

With this feature, users can generate arrays in different formats, like:

1. Default array (no indices):
   ["foo", "bar", "quz"]
2. With standard indices:
   [0: "foo", 1: "bar", 2: "quz"]
3. With JSON-style indices:
   ["0": "foo", "1": "bar", "2": "quz"]
4. With tuple indices:
   [(0,0): "foo", (0,1): "bar", (0,2): "quz"]
5. Custom formats (e.g., {index}={value}):
   [0="foo", 1="bar", 2="quz"]

Testing

• Added unit tests for standard indices display
• Added unit tests for the tuple indices display
• Added tests for various format templates
• Added UI tests for the new controls

Hi @fwdekker !! I don't know why this is showing as required verified signatures; no previous ones have shown this. Please help me resolve this issue. I have done the required modification with respect to the mentioned issue number

Don't worry about the signatures stuff. I assume it's because I enabled a feature on this repo that requires all commits to be signed. (This page explains what signing a commit is and how it is done.) I'll probably disable that requirement, but even if I don't, I'm not suddenly going to reject your PR because of it!

At a first glance, your PR looks very good! Thank you for the effort :-) I don't really have a lot of time on my hands to do an in-depth review right now, but once I do (later this week? after next week? not sure), I'll let you know right away!

It looks good! I've re-written some parts, most importantly combining all settings you added into a single setting, but in the end the core functionality is the same. :-)
