encoding/json: revert "add "json: " prefix to SyntaxError messages"
This reverts commit
6af088bfc66c13143c9ef46b4cf0805df77a8fbe.
Reason for revert: Broke many tests inside Google which implies many
tests were broken outside of Google as well. The tests may be brittle
but still would require work to change and it's not clear it's worth
the benefit.
Updates #36221
Fixes #42675
