Consider using an automated tool for changelog generatation

[BGluth]

I've been talking to @muursh & @Nashtare about potentially automating the generation of the changelog instead of manually updating it with each PR we merge back in. A few tools that were mentioned:

• git-cliff
• cargo-smart-release
• cargo-workspaces

Low priority, but if someone runs out of work, this might be worth spending some time looking at.

@BGluth this is already present in github Do we want some other functionality apart from this?

@temaniarpit27 So it's true that we could use this by only updating CHANGELOG.md each time we want to do a release by copying this from the release page... Idk if @muursh or @Nashtare have any thoughts here. I think any of the 3 above solutions would give us enough customizability to format the changelog lines in a format we like vs. the one that GitHub uses.
