Sort exclusions for data tables

Nobody has claimed this yet.

## Summary
Sort exclusions allow specific rows to be excluded from a sort so that they appear at the top or bottom of a sorted list.

## 💰 User value
This allows specific data to be pinned to top or bottom and be excluded from sort. This could be useful when certain values don't have content within a sortabel column.

## 📚 User Stories
If relevant, describe the high-level functionality as user stories.

*As an* ICDS developer
*I need* to be able to specify rows to be excluded from a sort
*So that* they can be positioned to top or bottom of a table regardless of sort.

## 📝 Acceptance Criteria
If relevant, describe in full detail the different interactions and edge cases that the component or patterns needs to fulfil.

*Given* that a data table exists with a column that is sortable,
*When* setting the data table column sort properties
*Then* specific rows can be excluded,
*and* the position of the excluded rows can be set to either 'top'(default) or 'bottom'.

## ✏ Designs
If there's a Figma design file (or other mock-up), include it here.

## 🧾 Guidance
If there's written guidance or documentation, include it here.

Start by locating the data table component and its sortable-column properties, then inspect how rows are currently ordered. Implement exclusion of specified rows with a configurable top or bottom position, and verify that the acceptance criteria hold for sortable columns and the default top position.
