[Enhancement] Remove Highchart Charts

[MadsBuchmann]

Please add a short description of your enhancement request
Once #1652 has been carried out and we know when to finally remove the old chart components - all of the old chart components should be removed.

Todo:

• Remove the kirby-chart-deprecated component
• Remove the kirby-stock-chart-deprecated component
• Remove associated cookbook pages for both
• Remove any & all dependencies to highcharts in package.json files!
• Ship it & celebrate with colleagues in close proximity! 🚣💨🕺💃

Additional context
This is part of an epic - please have a look at it: #1413
Also #1652 should be carried out before this task.

Also remember to remove the Stock Chart component: https://cookbook.kirby.design/home/showcase/stock-chart

It is not in use by any consumer projects and can safely be removed ☄️

@alxzak All blockers for this has been removed. Perhaps a candidate for the next major version?

[MadsBuchmann]

Scheduled for v7; a branch exists where highcharts and the components have been removed https://github.com/kirbydesign/designsystem/tree/enhancement/1578-remove-highchart-charts

Remember to rebase it once it's actually going to be used :-)

We need a PR for https://github.com/kirbydesign/designsystem/tree/enhancement/1578-remove-highchart-charts.
Consider creating a new base branch for release v7
