Remove the long-deprecated BooleanParameter

[Tarrasch]

Description

That parameter has been deprecated since way over one year. I believe also before 2.0.

The correct parameter to use is BoolParameter.

This will break so much code. I did not even know it was long deprecated ;) - but I guess is an easy-fix for existing code-base.

@mfcabrera, sure, but then you've ignored BooleanParameter is deprecated, use BoolParameter instead being printed out to your console for over a year. So my sympathy is not as high. But actually it's really good for me to know that people still use the deprecated version. I wish maintainers had more time to do deprecations properly, but that takes too much time.

FYI, BoolParameter was introduced in 1.0.21. BooleanParameter was deprecated in 2.0.0 and removed in 2.5.0.
