Retrieve/Count unresolved review comments

pr-unresolved-review-comments.sh

# Script Name: pr-unresolved-review-comments
#
# Description:
# This script is used to fetch unresolved review comments from a pull request in a Github repository. 
# The script uses Github's GraphQL API to query the repository and filter out resolved comments.
# It returns a list of unresolved comment threads, which can then be processed as per requirements.
#
# Usage:
# There are two general use cases for this script.
#
# 1. Retrieve unresolved review comments:
#    This will get all unresolved review comments from a particular pull request. 
#    Example usage:
#      ./pr-unresolved-review-comments myorganisation myrepo 1337
#
# 2. Count of unresolved review comment threads:
#    This will return the count of unresolved review comment threads in a pull request. 
#    To calculate the count we use 'jq' to find the length of the returned list.  
#    Example usage:
#      ./pr-unresolved-review-comments myorganisation myrepo 1337 | jq length
#
# Parameters:
#   - owner: It is the name of the organisation that owns the repository. It is passed as the first positional argument.
#   - repo: It is the name of the repository from where the pull request is made. It is passed as the second positional argument.
#   - pr: It is the number of the pull request. It is passed as the third positional argument.
#
# Output:
#   This script outputs a JSON data containing the unresolved comments information including author's login, body of the comment, url of the comment.
