Remove "semver" prefixes in documentation and tests

[arminru]

The semver prefix for versions was removed from the spec a while ago (open-telemetry/opentelemetry-specification#802, open-telemetry/opentelemetry-specification#873) but some Java tests and documentation including the quickstart guide are still using this notation:

opentelemetry-java/QUICKSTART.md

Lines 45 to 46 in c4791e9

	Tracer tracer =
	OpenTelemetry.getGlobalTracer("instrumentation-library-name","semver:1.0.0");

opentelemetry-java/QUICKSTART.md

Line 265 in c4791e9

Meter meter = OpenTelemetry.getGlobalMeter("instrumentation-library-name","semver:1.0.0");

opentelemetry-java/api/src/main/java/io/opentelemetry/api/OpenTelemetry.java

Lines 167 to 168 in c4791e9

	* @param instrumentationVersion The version of the instrumentation library (e.g.,
	* "semver:1.0.0").

opentelemetry-java/api/src/main/java/io/opentelemetry/api/trace/TracerProvider.java

Lines 44 to 45 in c4791e9

	* @param instrumentationVersion The version of the instrumentation library (e.g.,
	* "semver:1.0.0").

opentelemetry-java/sdk/common/src/test/java/io/opentelemetry/sdk/common/InstrumentationLibraryInfoTest.java

Line 26 in c4791e9

() -> InstrumentationLibraryInfo.create(null, "semver:1.0.0"),

opentelemetry-java/sdk/tracing/src/test/java/io/opentelemetry/sdk/trace/TracerSdkTest.java

Line 35 in c4791e9
