Workflow changed to commit json file to a branch

1. generate_sonic_image_links.sh is modified to checkout a dedicated branch(sonic_latest_images_links) and commit the sonic images links related json file to this branch.

2. json file from master branch is no more required and hence it is deleted.

3. html file updated to use the json file that is getting created in the branch
