Revert "Python 3.11: Enhanced error locations in tracebacks (#2771)" (#2839)

This reverts commit aa367302989978a1ae04badee7e3948502b96616.

It is no longer required on Python 3.11.0b4 and later; see
https://github.com/open-telemetry/opentelemetry-python/pull/2771#issuecomment-1193421508
and
https:f9d3b3a9e6267328a533d332ab32bc478d8c11ae@python.org/message/73YP4RS4QOJXUS63BQZVLTQHK3OP3L3H/.

Specifically, the ^^^^… are now omitted when they would “underline” the
whole preceding line, which is the case here, so the expected output is
the same as for Python 3.10 and earlier.
