docs: Readme release script

[brandenchan]

Proposed Changes:

• This script automatically creates a new release in Readme of Haystack docs
• It also updates the category id of API docs so they sync to the right place

TODO:

• [ ] Make it a github workflow
• [ ] implement logic that is sensitive to what kind of release (new version or incremental version)
