[Feature]: Create PR deployment preview candidate

[ramizpolic]

Problem Statement

It would be helpful if at the end of a specific PR, we could trigger a way to preview changes made on the UI/backend.
Something along the lines of /preview PR command that maintainers can invoke which would deploy the site.
I do not know how feasible this would be, so it would be useful to do scoping in advance.

Proposed Solution

Temporary PR website deployed to see the changes, e.g. a full website or even as a single docker command that says

You can preview changes of this PR via: docker run <pr-image>
