python: fix highlighting of built-in types for isinstance() and issub…

[csernazs]

When built-in types such as list is specified in calls like isinstance(), the parameter is highlighted as a type.

The issue is caused by a change which removed list and others in bf9e5b4f761b507310d744553e29ba6fdeb3c89a.

This commit makes two special cases for isinstance and issubclass ensuring tree sitter to highlight the parameters correctly.

Fixes #30331

Release Notes:

• python: Fixed syntax highlighting for isinstance() and issubclass() calls
