Playwright E2E Tests: Automating the loading of the *.txt files

[gigitux]

Currently, for each .txt file that is inside the folder bin, there is a specific command to save that template in WordPress (source code). Now, it is easy to maintain because we have few .txt files, but it will not be when there are more. So, we should create a dedicated script that automatically inserts all the posts/pages reading all the .txt.

Also, should we continue to use .txt as extension? If we use the .html, we could use the syntax highlight of the code editors.
