infra(netlify): enable deploy previews

[ST-DDT]

Fixes #815

• Make possible to preview docs of a PR on demand via netlify-preview #815

While technically not "on demand", this should sufficiently reduce (prevent) builds to not run into build-minute limits.

---

After this PR is merged, the feature has to be enabled in netlify.

Active Deploy Preview: ST-DDT#3
Skipped Deploy Preview: ST-DDT#4

Is it somehow possible to read a GitHub Label from the PR via netlify and when it exists, then do a preview?

Unfortunately not (yet).

Could we discuss in a meeting about this? How does it work? What are the downsides to consider? Can / Should we contact someone from netlify to ask if this is the best approach or if there is something better? and so on...

sure

Can / Should we contact someone from netlify to ask if this is the best approach or if there is something better?

We aren't the first asking for that feature.

Team Decision

We will merge this and reevaluate this in a month.

[ST-DDT]

Deploy previews enabled.

But it looks like I have to tweak the condition some more, so that "update from next" does not trigger a preview.
