Add GitHub Action to auto-sync wiki from a /docs (or /wiki) folder in the repository

[Ma77Ball]

Feature Summary

Currently, the Texera wiki can only be edited by project committers with direct write access to the GitHub wiki. This creates a bottleneck for documentation contributions from community members who can submit PRs but cannot edit the wiki directly. This feature would add a GitHub Action that automatically syncs a dedicated folder in the main repository (e.g., docs/wiki/) to the GitHub wiki on every merge to the main branch, enabling anyone to contribute documentation improvements via the standard PR workflow.

Proposed Solution or Design

Add a GitHub Actions workflow (.github/workflows/sync-wiki.yml) that triggers on pushes to main and uses an existing action such as newrelic-forks/github-wiki-publish-action or Andrew-Chen-Wang/github-wiki-action to push the contents of a designated folder to the wiki.

When we move to Apache.org page (I.e, docs/), do we still need GitHub wiki?

[chenlica]

A general question is whether we should use GitHub wiki or Apache.org for such docs. What do other Apache projects do?

[Yicong-Huang]

Spark, arrow, iceberg, airflow are all using Apache docs, not wiki.

I think we discussed before and wiki can serve as a temporary location for docs. But for the long term we will migrate to host docs on Apache.org, as we can generate it ourselves and have more control. It is also required for graduation from incubation.

Then I agree with the idea of using Apache docs for such info. @Ma77Ball Can you suggest a way to streamline the process?

[Ma77Ball]

We are still using the wiki for now, and this is an improvement in the short term. We have some of the docs on the website (the website is the Apache docs texera.apache.org) (from what I saw in the Spark and Arrow docs). As the website is still a work in progress by other members of the team, and there is no voted-upon standard for everyone to use only the website docs, I think this PR is still valid.

I am OK with using this new process as a temporary way to improve our wiki, before we move the content to the Apache.org site.
