meta: Remove PR template tests pass checkbox

[bruno-garcia]

📜 Description

Removed a check box.

💡 Motivation and Context

I need to wait for CI to see if it passed before I can check the checkbox. No much value in that.

💚 How did you test it?

📝 Checklist

• I reviewed submitted code
• I added tests to verify changes
• All tests passing
• No breaking changes

🔮 Next steps

#skip-changelog

so you know that you need to run the build/tests locally :) that's the value.
at least for me, its helpful, sometimes I forget to run the tests and they are broken, that checkbox makes me do that.
no strong opinions here, maybe @philipphofmann

I'm fine with removing it. If you forgot to run them locally, the CI is going to tell you.
