Move PipeCD docs hosting to Netlify

[rahulshendre]

Currently the PipeCD docs site is managed through the existing infrastructure setup.

Since the docs site is static, maintaining the current setup may add unnecessary infrastructure and maintenance overhead. We should explore migrating docs hosting to a simpler static hosting platform such as Netlify

Things that would need to be handled:

• current deployment workflow
• versioned docs support
• redirects/routing
• DNS/config updates

Feel free to share suggestions, concerns, or alternative approaches before implementation begins.

Note: this would likely be an end-to-end ownership task, so please take it up only if you are serious about handling the migration properly.

@khanhtc1202 PTAL and please verify if the current issue description assumptions look correct before we start working on this

what we’re optimizing for?
From the repo it looks like the site is currently built into a container + Helm chart (and /docs/ redirects to the latest version). If we move to Netlify, do we want to keep the exact same URL/versioning behavior (including the /docs/ → latest redirect) and also add PR preview deploys for doc changes? Knowing that upfront would make the migration plan much clearer.

If helpful, we could also add a short list of expected outcomes for this migration (e.g., reduce maintenance, keep URL/version behavior, add PR previews) so it’s clear what “done” looks like.
