Add a new blueprint for getting an empty installation of WordPress (using resetData)

[juanmaguitar]

This blueprint runs an SQL query to delete default posts from the default theme.
It also loads custom content with custom IDs for each post.
The technique used in this blueprint is a nice workaround for this issue.

Test using WordPress Playground

The changes in this pull request can previewed and tested using a WordPress Playground instance.

WordPress Playground is an experimental project that creates a full WordPress instance entirely within the browser.

Some things to be aware of

• The Plugin and Theme Directories cannot be accessed within Playground.
• All changes will be lost when closing a tab with a Playground instance.
• All changes will be lost when refreshing the page.
• A fresh instance is created each time the link below is clicked.
• Every time this pull request is updated, a new ZIP file containing all changes is created. If changes are not reflected in the Playground instance,
  it's possible that the most recent build failed, or has not completed. Check the list of workflow runs to be sure.

For more details about these limitations and more, check out the Limitations page in the WordPress Playground documentation.

Instead of running the Delete queries, try the new "resetData" step

The title and the description need adjusting as runSql isn't really used here. Otherwise it looks good, thank you @juanmaguitar!
