[3.8] bpo-42589: Change URL for 'from' link when used in a raised exc… (GH-25755)

…eption (GH-23872)

Links for 'raise Exception from x' target to 'The raise statement' (7.8) section instead of 'The import statement' (7.11) section.

There are more modified links than in the bug report because I searched some other ones which can get the same improvement..
(cherry picked from commit 2fd928c)

This PR is a cherry pick to python 3.8 from #23872. The fix was the removal of the change in the other file because the fixed section was introduced in 3.9. So the file does not need to be fixed in 3.8.
