[issue14679] Define an __all__ for html.parser

[Senthil Kumaran]

Senthil Kumaran added the comment:

I think, HTMLParseError should also be defined __all__ (all also servers as what public classes/methods to look for sometimes and sets some expectation while reading the code.) 

There is no deprecation warning added in the class here.
