Remove stepper buttons from tab order

[ikanishakm]

What is this PR doing
This pull request adjusts the tab order for the Stepper component buttons by setting their tabIndex to -1. This change removes the increment and decrement buttons from the keyboard tab sequence, potentially improving navigation for keyboard users.

Testing

• Verify tab order behavior

  • Open a page containing the Stepper component
  • Use the Tab key to navigate through the page
  • Confirm that focus skips over the increment and decrement buttons
  • Verify that focus moves directly from the input field to the next focusable element

• Check button functionality

  • Click on the increment and decrement buttons with a mouse
  • Confirm that the buttons still function correctly when clicked

• Keyboard accessibility check

  • Focus on the Stepper input field
  • Attempt to use arrow keys or other keyboard shortcuts to increment/decrement the value
  • Note any unexpected behavior or lack of keyboard control

Thank you for your contribution!

However, removing the stepper buttons from the tab order by setting their ‎tabIndex to -1 would make these controls inaccessible to keyboard and assistive technology users. Accessible interfaces require that all interactive elements, including increment and decrement buttons, remain reachable via keyboard.
