Use "deselect" instead of "unselecet" for checkboxes

[hsnabszhdn]

Why:

The word "unselect" does not follow the style guide:

To describe choosing or clearing a checkbox, use “select” or “deselect.”

Closes: N/A

What's being changed (if available, include any code snippets, screenshots, or gifs):

The term "unselect" changes to "deselect".
