Restore some opentelemetry module mappings (Cherry-pick of #20749) (#20753)

Several of mappings for opentelemetry packages were added/adjusted in
#20551 and then adjusted more in #20705, but the second adjustment was
based on the default fallback mapping replacing `-` with `.`, but it
actually replaces them with `_`. This restores explicit mappings for the
following (where I've downloaded the wheels and verified their
contents):

- `opentelemetry-exporter-otlp`
- `opentelemetry-exporter-otlp-proto-grpc`
- `opentelemetry-exporter-otlp-proto-http`
- `opentelemetry-sdk`

These were originally added in #16337, released in 2.14.0, so this would
be a notable regression if we released 2.20.0 without them.

Noticed in
#20705 (comment)
