refactor(plans): Rename piTest Tests

@tboehler1 I would like to have more consistency in the pt Tests... (piTest)

In the description of the Tests we can read:

Test the piBridge and communication with modules using piTest.

That's why I suggest a new name for the tests...

The idea is to improve this:

And this...

What currently seems like a disaster to me...

After the change, we will only have a single row with tests, where we will see all devices...

What do you think about piTest_piBridge_Tests ?
