fix(cpn): selection of sound packs in update process

[elecpower]

Fixes #3841

Summary of changes:

• refactor asset filtering to not use sounds.json file but instead filter the release assets
• only 1 pack can be downloaded per run as all language variants share the same destination directory
• supporting functions
• housekeeping

Due to a change to the asset filter a release note is required as only 1 zip file will be found for each language with the old filter:
Steps:

1. Launch Companion
2. Select Settings
3. Select Update Settings tab
4. Click Sounds component Options button
5. Edit the Filter pattern by DELETING the trailing hypen
6. Click OK to save the change
7. Click OK to exit the Settings

There may be an issue where you have run the updater twice in a row, and pick a different sound pack each time? It prompts you to download it again, and then unpacks it. Although, unrelated to this PR it seems as I can get something similar to happen with 2.9.0. Otherwise seems to be working (Windows 11, EN packs).
