Code Quality: Format XML files & Add prefixes to BackgroundTasks project name

I didn't want to create separate branches for those.

Motivation & Context

• Improved readability

Warning
Please do not review code lines that I did not changed. I cannot make more diff. If there're more codes that are preferred to change, I will do that and mark that PR as the final one for that stage.

Do you have any idea to fix the auto updating issue?

We can make it work if we split it into two steps

1. Update this url and release an update with the change
2. Rename the projects in another update
