PipeCD - Blog Contribution Guide

Wrote the guide that shows community members how to contribute blog posts to PipeCD, including format rules and how to submit a post.

I created the blog contribution guide for PipeCD so community members have a clear path to propose and publish technical posts.

The guide covers what kind of content is expected, the frontmatter and format rules, and how submission and review work.

I also made the docs structure match across docs-dev and docs-v1.0.x, including a section rename to keep the contribution docs consistent.

This was part of the wider contributor-docs effort in issue #6124, and it merged after maintainer review.
