Feature : Setup tools that will auto generate changelogs.

### Is your feature request related to a problem? Please describe.

Currently we follow a style of commit similar to one mentioned [here](https://www.conventionalcommits.org/en/v1.0.0/). There are many tools that can auto generate changelogs and also this type of convention helps us review the commits if something goes wrong.

### Describe the solution you'd like

Setup these tools that will automatically generate change logs.

### Additional context

Also explore if these tools can enforce the convention only for maintainers when they merge and not on contributors ( as rebasing can be pretty hard for first timers).
