[issue43556] fix attr names for ast.expr and ast.stmt

[Samwyse]

New submission from Samwyse <samwyse at gmail.com>:

In Doc/library/ast.rst, the lineno and end_col attributes are repeated; the second set should have 'end_' prefixed to them.  Also, there's a minor indentation error in the RST file.

# diff ast.rst ast.rst~

<                   col_offset
---
>                         col_offset
83c83
<       :attr:`lineno`, :attr:`col_offset`, :attr:`end_lineno`, and :attr:`end_col_offset`
---
>       :attr:`lineno`, :attr:`col_offset`, :attr:`lineno`, and :attr:`col_offset`
