Add kbidani as project contributor

[erwango]

Background

The TSC Project Roles defines the main roles for the Zephyr Project, including
Maintainer, Collaborator, and Contributor.

By default anyone that contributes code or documentation is a Contributor, but
with the lowest GitHub Permission Level of Read. For example, Contributors
with Read permission do not have the permission to add reviewers to a pull
request.

Use this template to nominate a GitHub user for the Contributor role with
Triage permission level, which allows the user to add reviewers to a pull
request and be added as a reviewer by other users.
