[table] hideColumn and showColumn don't update hidden property in column configuration

[eliganemtyler]

Describe the bug:
The forge TableComponent hideColumn and showColumn methods don't update the hidden property of the columnConfiguration

To Reproduce:
Steps to reproduce the behavior:

1. Go to the forge demo app table page
2. In pages/table.ts set the hidden property of one columnConfiguration to true
3. Add a "show" button, "hide" button, and "log" button to table.ejs
4. Add event listeners to each button to show the hidden column, hide a visible column, and console.log(table.columnConfigurations respectively
5. Hit each button
6. In the console, the shown column has a hidden: true and the hidden column has hidden undefined.

Expected behavior:
The hideColumn and showColumn methods should update the columnConfiguration hidden properties.

Please complete the following information:

• Forge version: 2.24.1

Additional context:
You often use the hidden value of a columnConfiguration to filter out hidden columns in cases like using the ITableFilterEventData columnIndex value to get the matching visible columnConfiguration. The event data columnIndex correctly updates both when columns are hidden/shown by setting columnConfiguration.hidden manually or via hideColumn/showColumn, but there's no way to match columnIndex to the visible column in the latter case because the hidden property isn't updated.
