Automate setting date in the header

[sreeram-venkitesh]

We have a date field in the markdown header/frontmatter for every post.

---
layout: post
title: Week Ending November 3, 2024
date: 2024-11-03 22:00:00 -0000
slug: 2024-11-03-update
---

Currently the date is updated manually before publishing. The date value cannot be in the future, else it won't show up in the website. Having a wrong date would also mess up RSS feeds. The date should be set to whatever time we are publishing the newsletter/merge the PR to main. We can possibly automate this with a git hook that fires after every commit or before we merge the PR in GitHub.
