CHANGELOG.md creation

Create CHANGELOG.md

Description

I wrote a node.js script that generates CHANGELOG.md from changelog.txt.
What the script does is.

1. Read the changelog.txt
2. Extract the data
3. Make changes where needed
4. Write the data to CHANGELOG.md

And also if you pass --generate-json as a CLI parameter to the script, it will write the extracted data to changelog-data.json.

Motivation and Context

In the changelog, contributors may want to refer to an issue or to a link which is related to a specific change. In plain text, it can be achievable, but markdown would be more suitable.

How Has This Been Tested?

I ran node generate-changelog.js and everything worked out as I expected.
The script created CHANGELOG.md using the content from changelog.txt

node: v12.19.0
