feat(segment, segment-button): update segment value property to accept numbers (#27222)

Issue number: resolves #27221

---------

## What is the current behavior?

The value property of the segment component in Ionic Framework currently
only accepts string values.

## What is the new behavior?

This pull request updates the "value" property of the segment component
to accept a union of string and number types. This allows for more
versatile data input in the segment component, particularly for users
who work with numerical data.

## Does this introduce a breaking change?

- [ ] Yes
- [X] No
