*Seeking Contribution* PRs from forks are not generating preview builds.

[stoobie]

Describe the bug

When a PR originates from a forked repo, it does not generate an HTML preview to enable reviewing and testing the PR in a browser prior to merging.

The issue becomes visible when the runner runs the Commit changes step in the pull_requent.yml workflow.

To Reproduce
Steps to reproduce the behavior:

1. Fork (and optionally clone) the starknet-docs repo.
2. Create a new branch and make a small change in an .adoc file.
3. Push the new branch and create a new PR.

Expected behavior
You should see this in Conversaton tab of the PR

You should also see a link like this one (with the correct PR-number):

So far I've been unable to fix this issue. If you want to take a look and try to fix it, your contribution will be very much appreciated.

This is a duplicate of #1043

Unfortunately, #1182 was required to revert the PRs #1097 and #1152 of the pull_request_target event.

So we are back to where we started with this one.

I am very sorry. Let other people come to resolve it firstly.

Generally speaking, the pull_request_target event is more security than pull_request event, maybe there is something wrong with the token.
