"parameterized generic" should be "argumentized generic type"

Bug report

Bug description:

Setting a generic type with a type specification [] to isinstance() and issubclass() gets the wrong error messages as shown below:

*Notes:

• Python 3.15.0a6

x = 100

isinstance(x, tuple)           # No error
isinstance(x, tuple[int, str]) # Error

TypeError: isinstance() argument 2 cannot be a parameterized generic

class Cls: ...

issubclass(Cls, tuple)           # No error
issubclass(Cls, tuple[int, str]) # Error

TypeError: issubclass() argument 2 cannot be a parameterized generic

Actually, saying "parameterized" reminds function parameters so "argumentized" should be used and "type" should also be used after "generic" as shown below:

*Notes:

• "argumentized" isn't common but intuitive.

TypeError: isinstance() argument 2 cannot be an argumentized generic type

TypeError: issubclass() argument 2 cannot be an argumentized generic type

parameterized
argumentized

"parametrized" is correct; it's a common word to mean indicate that the parameters were filled (in contrast to "parametrizable"). And once again, if you decide to ignore my warning about "not creating PRs until we decide to address this issue", we will have no choice but to restrict your access to the repository as this creates too much noise.
