[Bug]: LocalSpannerIO package namespace conflict with Beam's SpannerIO #1362

What happened?
V1 templates use LocalSpannerIO under Beam's namespace: https://github.com/GoogleCloudPlatform/DataflowTemplates/tree/main/v1/src/main/java/org/apache/beam/sdk/io/gcp/spanner and depends on beam-sdks-java-io-google-cloud-platform as well, causing unpredictable class conflict.
It happens in the 2.55.0 release validation: #1361 SpannerIO V1 templates failed with error
Caused by: java.lang.NoSuchMethodError: 'org.apache.beam.sdk.options.ValueProvider org.apache.beam.sdk.io.gcp.spanner.SpannerConfig.getCredentials()'

because SpannerAccessor was picked from beam-io-gcp but SpannerConfig was picked from v1 at run time, causing NoSuchMethodError.
We should either relocate the namespace of LocalSpannerIO or migrate to Beam's SpannerIO
