Remove the `initUnit("1", "ratio")` mapping and treat unit "1" as
unitless (returning null from convertUnit), aligning with the spec
change in open-telemetry/opentelemetry-specification#4966.
This also handles the edge case where "1" remains after stripping
curly-brace annotations (e.g. "1{dropped}").
Fixes open-telemetry#8237
